Medium Mathematics Quadratic Equations Class 10 Level 30

समीकरण ((x+4)2-3(x+4)-10=0) को सरल करने पर कौन-सा द्विघात समीकरण मिलेगा?

Which quadratic equation is obtained by simplifying ((x+4)2-3(x+4)-10=0)?

Explanation opens after your attempt
Correct Answer

A. \(x^2+5x-6=0\)

Step 1

Concept

((x+4)2=x-2+8x+16) and (-3(x+4)=-3x-12). Simplifying gives \(x^2+5x-6=0\).

Step 2

Why this answer is correct

The correct answer is A. \(x^2+5x-6=0\). ((x+4)2=x-2+8x+16) and (-3(x+4)=-3x-12). Simplifying gives \(x^2+5x-6=0\).

Step 3

Exam Tip

((x+4)2=x-2+8x+16) और (-3(x+4)=-3x-12) है। सरल करने पर \(x^2+5x-6=0\) मिलता है।
