Question 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 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 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।
