Question 1/7 Medium Mathematics Polynomials Representing real numbers on the number line Class 10 Level 50

संख्या रेखा पर (r(x)=4x+6) का शून्यक किस अंतराल में होगा?

In which interval will the zero of (r(x)=4x+6) lie on the number line?

Explanation opens after your attempt
Correct Answer

A. (-2) और (-1)(-2) and (-1)

Step 1

Concept

From (4x+6=0), \(x=-\frac{3}{2}\), which lies between (-2) and (-1). In exams, identify the interval of a negative fraction carefully.

Step 2

Why this answer is correct

The correct answer is A. (-2) और (-1) / (-2) and (-1). From (4x+6=0), \(x=-\frac{3}{2}\), which lies between (-2) and (-1). In exams, identify the interval of a negative fraction carefully.

Step 3

Exam Tip

(4x+6=0) से \(x=-\frac{3}{2}\), जो (-2) और (-1) के बीच है। परीक्षा में ऋणात्मक भिन्न का अंतराल सावधानी से पहचानें।

Question 2/7 Expert Mathematics Polynomials Polynomials in one variable Class 10 Level 46

यदि (p(x)=ax+b) और \(a\neq0\), तो इसका शून्यक क्या है?

If (p(x)=ax+b) and \(a\neq0\), what is its zero?

Explanation opens after your attempt
Correct Answer

A. -\(\frac{b}{a}\)

Step 1

Concept

Putting (ax+b=0) gives \(x=-\frac{b}{a}\). A linear polynomial has exactly one zero.

Step 2

Why this answer is correct

The correct answer is A. -\(\frac{b}{a}\). Putting (ax+b=0) gives \(x=-\frac{b}{a}\). A linear polynomial has exactly one zero.

Step 3

Exam Tip

(ax+b=0) रखने पर \(x=-\frac{b}{a}\) मिलता है। रेखीय बहुपद में केवल एक शून्यक होता है।

Question 3/7 Medium Mathematics Polynomials Polynomials in one variable Class 10 Level 48

यदि (p(x)=cx+d) और \(c\ne0\), तो इसका शून्य क्या होगा?

If (p(x)=cx+d) and \(c\ne0\), what will be its zero?

Explanation opens after your attempt
Correct Answer

B. \(-\frac{d}{c}\)

Step 1

Concept

From (cx+d=0), we get \(x=-\frac{d}{c}\). Remember the negative sign in the formula.

Step 2

Why this answer is correct

The correct answer is B. \(-\frac{d}{c}\). From (cx+d=0), we get \(x=-\frac{d}{c}\). Remember the negative sign in the formula.

Step 3

Exam Tip

(cx+d=0) से \(x=-\frac{d}{c}\) मिलता है। सूत्र में ऋण चिह्न ध्यान रखें।

Question 4/7 Medium Mathematics Polynomials Polynomials in one variable Class 10 Level 48

(p(x)=9x-27) का शून्य क्या है?

What is the zero of (p(x)=9x-27)?

Explanation opens after your attempt
Correct Answer

B. (3)

Step 1

Concept

From (9x-27=0), we get (x=3). Find the zero of a linear polynomial by solving the equation.

Step 2

Why this answer is correct

The correct answer is B. (3). From (9x-27=0), we get (x=3). Find the zero of a linear polynomial by solving the equation.

Step 3

Exam Tip

(9x-27=0) से (x=3) मिलता है। रैखिक बहुपद का शून्य समीकरण हल करके निकालें।

Question 5/7 Medium Mathematics Polynomials Polynomials in one variable Class 10 Level 46

यदि (p(x)=ax+b) और \(a\ne0\), तो इसका शून्य क्या होगा?

If (p(x)=ax+b) and \(a\ne0\), what will be its zero?

Explanation opens after your attempt
Correct Answer

B. \(-\frac{b}{a}\)

Step 1

Concept

From (ax+b=0), we get \(x=-\frac{b}{a}\). Remember the general formula but do not miss the sign.

Step 2

Why this answer is correct

The correct answer is B. \(-\frac{b}{a}\). From (ax+b=0), we get \(x=-\frac{b}{a}\). Remember the general formula but do not miss the sign.

Step 3

Exam Tip

(ax+b=0) से \(x=-\frac{b}{a}\) मिलता है। सामान्य सूत्र याद रखें लेकिन संकेत न भूलें।

Question 6/7 Medium Mathematics Polynomials Polynomials in one variable Class 10 Level 46

(p(x)=7x-14) का शून्य क्या है?

What is the zero of (p(x)=7x-14)?

Explanation opens after your attempt
Correct Answer

B. (2)

Step 1

Concept

From (7x-14=0), we get (x=2). Solve the equation to find the zero of a linear polynomial.

Step 2

Why this answer is correct

The correct answer is B. (2). From (7x-14=0), we get (x=2). Solve the equation to find the zero of a linear polynomial.

Step 3

Exam Tip

(7x-14=0) से (x=2) मिलता है। रैखिक बहुपद का शून्य जल्दी निकालने के लिए समीकरण हल करें।

Question 7/7 Medium Mathematics Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 22

रेखा (y=-3x-12) का शून्यक क्या है?

What is the zero of the line (y=-3x-12)?

Explanation opens after your attempt
Correct Answer

B. (-4)

Step 1

Concept

Solving (-3x-12=0) gives (x=-4). Tip: put (y=0) to find the linear zero.

Step 2

Why this answer is correct

The correct answer is B. (-4). Solving (-3x-12=0) gives (x=-4). Tip: put (y=0) to find the linear zero.

Step 3

Exam Tip

(-3x-12=0) से (x=-4) मिलता है। टिप: (y=0) रखकर रैखिक शून्यक निकालें।
