Question 1/4 Hard Mathematics Polynomials Polynomials in one variable Class 10 Level 46

किस बहुपद के शून्यक (0), (2) और (-3) हैं?

Which polynomial has zeroes (0), (2), and (-3)?

Explanation opens after your attempt
Correct Answer

A. \(x^3+x^2-6x\)

Step 1

Concept

From the zeroes, the polynomial is (x(x-2)(x+3)). Expanding gives \(x^3+x^2-6x\).

Step 2

Why this answer is correct

The correct answer is A. \(x^3+x^2-6x\). From the zeroes, the polynomial is (x(x-2)(x+3)). Expanding gives \(x^3+x^2-6x\).

Step 3

Exam Tip

शून्यकों से बहुपद (x(x-2)(x+3)) बनेगा। इसे फैलाने पर \(x^3+x^2-6x\) मिलता है।

Question 2/4 Hard Mathematics Polynomials Polynomials in one variable Class 10 Level 46

यदि द्विघात बहुपद के शून्यक \(\alpha\) और \(\beta\) हैं तथा \(\alpha+\beta=5\), \(\alpha\beta=6\), तो मोनिक बहुपद क्या है?

If a quadratic polynomial has zeroes \(\alpha\) and \(\beta\), with \(\alpha+\beta=5\) and \(\alpha\beta=6\), what is the monic polynomial?

Explanation opens after your attempt
Correct Answer

A. \(x^2-5x+6\)

Step 1

Concept

The monic polynomial is (x-2-\(\alpha+\beta\)x+\alpha\beta). Hence \(x^2-5x+6\) is correct.

Step 2

Why this answer is correct

The correct answer is A. \(x^2-5x+6\). The monic polynomial is (x-2-\(\alpha+\beta\)x+\alpha\beta). Hence \(x^2-5x+6\) is correct.

Step 3

Exam Tip

मोनिक बहुपद (x-2-\(\alpha+\beta\)x+\alpha\beta) होता है। इसलिए \(x^2-5x+6\) सही है।

Question 3/4 Hard Mathematics Polynomials Polynomials in one variable Class 10 Level 46

द्विघात बहुपद जिसके शून्यक \(\frac{2}{3}\) और \(-\frac{5}{4}\) हैं, कौन सा हो सकता है?

Which can be a quadratic polynomial whose zeroes are \(\frac{2}{3}\) and \(-\frac{5}{4}\)?

Explanation opens after your attempt
Correct Answer

A. \(12x^2+7x-10\)

Step 1

Concept

The sum is \(-\frac{7}{12}\) and the product is \(-\frac{5}{6}\). So \(12x^2+7x-10\) is correct.

Step 2

Why this answer is correct

The correct answer is A. \(12x^2+7x-10\). The sum is \(-\frac{7}{12}\) and the product is \(-\frac{5}{6}\). So \(12x^2+7x-10\) is correct.

Step 3

Exam Tip

शून्यकों का योग \(-\frac{7}{12}\) और गुणनफल \(-\frac{5}{6}\) है। इसलिए \(12x^2+7x-10\) सही है।

Question 4/4 Easy Mathematics Quadratic Equations Introduction to Quadratic Equations Class 10 Level 30

किसी संख्या (x) के वर्ग में उसके (3) गुने को जोड़ने पर (10) मिलता है। सही समीकरण कौन-सा है?

The square of a number (x) plus (3) times the number is (10). Which equation is correct?

Explanation opens after your attempt
Correct Answer

B. \(x^2+3x=10\)

Step 1

Concept

Square means \(x^2\) and (3) times means (3x). In word problems, convert the sentence slowly into an equation.

Step 2

Why this answer is correct

The correct answer is B. \(x^2+3x=10\). Square means \(x^2\) and (3) times means (3x). In word problems, convert the sentence slowly into an equation.

Step 3

Exam Tip

वर्ग का अर्थ \(x^2\) और (3) गुना का अर्थ (3x) है। शब्द प्रश्न में वाक्य को धीरे-धीरे समीकरण में बदलें।
