What are the roots of \(x^2-7x+10=0\)?
Explanation opens after your attempt
A. (x=2,5)
Concept
(x-2-7x+10=(x-2)(x-5)), so the roots are (2) and (5). In exams, check (2+5=7) and \(2\times5=10\).
Why this answer is correct
The correct answer is A. (x=2,5). (x-2-7x+10=(x-2)(x-5)), so the roots are (2) and (5). In exams, check (2+5=7) and \(2\times5=10\).
Exam Tip
(x-2-7x+10=(x-2)(x-5)), इसलिए मूल (2) और (5) हैं। परीक्षा में (2+5=7) और \(2\times5=10\) जांचें।
