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