Question Easy Mathematics Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 23

ग्राफ में बिंदु ((-8,0)) दिखने पर बहुपद का कौन-सा मान शून्य होगा?

If the point ((-8,0)) appears on the graph, which value of the polynomial input gives zero?

Explanation opens after your attempt
Correct Answer

A. (x=-8)

Step 1

Concept

The point ((-8,0)) means (y=0) at (x=-8). So (x=-8) makes the polynomial zero.

Step 2

Why this answer is correct

The correct answer is A. (x=-8). The point ((-8,0)) means (y=0) at (x=-8). So (x=-8) makes the polynomial zero.

Step 3

Exam Tip

((-8,0)) का अर्थ है (x=-8) पर (y=0)। इसलिए (x=-8) बहुपद को शून्य बनाता है।

Question Expert Mathematics Polynomials Irrational numbers and real numbers Class 10 Level 25

यदि (p(x)=x-2-2x-2) है, तो (p\(1+\sqrt{3}\)) क्या है?

If (p(x)=x-2-2x-2), what is (p\(1+\sqrt{3}\))?

Explanation opens after your attempt
Correct Answer

A. (0)

Step 1

Concept

(\(1+\sqrt{3}\)2-2\(1+\sqrt{3}\)-2=1+2\sqrt{3}+3-2-2\sqrt{3}-2=0). Do not forget the middle term while expanding the square.

Step 2

Why this answer is correct

The correct answer is A. (0). (\(1+\sqrt{3}\)2-2\(1+\sqrt{3}\)-2=1+2\sqrt{3}+3-2-2\sqrt{3}-2=0). Do not forget the middle term while expanding the square.

Step 3

Exam Tip

(\(1+\sqrt{3}\)2-2\(1+\sqrt{3}\)-2=1+2\sqrt{3}+3-2-2\sqrt{3}-2=0)। वर्ग खोलते समय बीच का पद न भूलें।

Question Expert Mathematics Polynomials Irrational numbers and real numbers Class 10 Level 25

यदि (p\(\sqrt{5}\)=0) और (p(x)=x-2+ax-5) है, तो (a) का मान क्या है?

If (p\(\sqrt{5}\)=0) and (p(x)=x-2+ax-5), what is the value of (a)?

Explanation opens after your attempt
Correct Answer

A. (0)

Step 1

Concept

Substitution gives \(5+a\sqrt{5}-5=0\), so \(a\sqrt{5}=0\) and (a=0). Simplify like terms first while substituting.

Step 2

Why this answer is correct

The correct answer is A. (0). Substitution gives \(5+a\sqrt{5}-5=0\), so \(a\sqrt{5}=0\) and (a=0). Simplify like terms first while substituting.

Step 3

Exam Tip

रखने पर \(5+a\sqrt{5}-5=0\), इसलिए \(a\sqrt{5}=0\) और (a=0)। मान रखते समय समान पद पहले सरल करें।

Question Hard Mathematics Polynomials Irrational numbers and real numbers Class 10 Level 27

यदि (p(x)=x-2-2x-2) है, तो (p\(\sqrt{2}\)) का मान क्या है?

If (p(x)=x-2-2x-2), what is the value of (p\(\sqrt{2}\))?

Explanation opens after your attempt
Correct Answer

A. \(-2\sqrt{2}\)

Step 1

Concept

(p\(\sqrt{2}\)=\(\sqrt{2}\)2-2\sqrt{2}-2=2-2\sqrt{2}-2=-2\sqrt{2}). When substituting, write (\(\sqrt{2}\)2=2).

Step 2

Why this answer is correct

The correct answer is A. \(-2\sqrt{2}\). (p\(\sqrt{2}\)=\(\sqrt{2}\)2-2\sqrt{2}-2=2-2\sqrt{2}-2=-2\sqrt{2}). When substituting, write (\(\sqrt{2}\)2=2).

Step 3

Exam Tip

(p\(\sqrt{2}\)=\(\sqrt{2}\)2-2\sqrt{2}-2=2-2\sqrt{2}-2=-2\sqrt{2}) है। मान रखते समय (\(\sqrt{2}\)2=2) लिखें।
