समीकरण ((x-2)(x+3)+(2x-1)(x-4)=0) का मानक रूप कौन-सा है?
What is the standard form of ((x-2)(x+3)+(2x-1)(x-4)=0)?
Explanation opens after your attempt
A. \(3x^2-8x-2=0\)
Concept
Here ((x-2)(x+3)=x-2+x-6) and ((2x-1)(x-4)=2x-2-9x+4). Adding them gives \(3x^2-8x-2=0\).
Why this answer is correct
The correct answer is A. \(3x^2-8x-2=0\). Here ((x-2)(x+3)=x-2+x-6) and ((2x-1)(x-4)=2x-2-9x+4). Adding them gives \(3x^2-8x-2=0\).
Exam Tip
((x-2)(x+3)=x-2+x-6) और ((2x-1)(x-4)=2x-2-9x+4) है। जोड़ने पर \(3x^2-8x-2=0\) मिलता है।
