Question 1/3 Medium Mathematics Quadratic Equations Introduction to Quadratic Equations Class 10 Level 30

किसी संख्या (x) के वर्ग में उसके (9) गुने को घटाने पर (36) मिलता है। सही समीकरण कौन-सा है?

When (9) times a number (x) is subtracted from its square, the result is (36). Which equation is correct?

Explanation opens after your attempt
Correct Answer

A. \(x^2-9x-36=0\)

Step 1

Concept

The statement gives \(x^2-9x=36\). Bringing all terms to one side gives \(x^2-9x-36=0\).

Step 2

Why this answer is correct

The correct answer is A. \(x^2-9x-36=0\). The statement gives \(x^2-9x=36\). Bringing all terms to one side gives \(x^2-9x-36=0\).

Step 3

Exam Tip

वाक्य से \(x^2-9x=36\) बनता है। सभी पद एक ओर लाने पर \(x^2-9x-36=0\) मिलता है।

Question 2/3 Medium Mathematics Quadratic Equations Introduction to Quadratic Equations Class 10 Level 29

किसी संख्या (x) का वर्ग उसके (5) गुने से (24) अधिक है। सही समीकरण कौन-सा है?

The square of a number (x) is (24) more than (5) times it. Which equation is correct?

Explanation opens after your attempt
Correct Answer

A. \(x^2-5x-24=0\)

Step 1

Concept

The statement gives \(x^2=5x+24\). Bringing all terms to one side gives \(x^2-5x-24=0\).

Step 2

Why this answer is correct

The correct answer is A. \(x^2-5x-24=0\). The statement gives \(x^2=5x+24\). Bringing all terms to one side gives \(x^2-5x-24=0\).

Step 3

Exam Tip

वाक्य से \(x^2=5x+24\) बनता है। सभी पद एक ओर लाने पर \(x^2-5x-24=0\) मिलता है।

Question 3/3 Medium Mathematics Quadratic Equations Introduction to Quadratic Equations Class 10 Level 28

एक संख्या और उसके वर्ग का योग (42) है। सही समीकरण कौन-सा है?

The sum of a number and its square is (42). Which equation is correct?

Explanation opens after your attempt
Correct Answer

A. \(x^2+x-42=0\)

Step 1

Concept

The sentence gives \(x^2+x=42\), that is \(x^2+x-42=0\). In word problems, write the algebraic form first.

Step 2

Why this answer is correct

The correct answer is A. \(x^2+x-42=0\). The sentence gives \(x^2+x=42\), that is \(x^2+x-42=0\). In word problems, write the algebraic form first.

Step 3

Exam Tip

वाक्य से \(x^2+x=42\) बनता है, यानी \(x^2+x-42=0\)। शब्द प्रश्न में पहले बीजीय रूप लिखें।
