यदि (p(x)=3x-7) और (q(x)=2x+5), तो (p(x)+q(x)) क्या है?
If (p(x)=3x-7) and (q(x)=2x+5), what is (p(x)+q(x))?
Explanation opens after your attempt
A. (5x-2)
Concept
Adding like terms gives (3x+2x=5x) and (-7+5=-2). Therefore the sum is (5x-2).
Why this answer is correct
The correct answer is A. (5x-2). Adding like terms gives (3x+2x=5x) and (-7+5=-2). Therefore the sum is (5x-2).
Exam Tip
समान पद जोड़ने पर (3x+2x=5x) और (-7+5=-2) मिलता है। इसलिए योग (5x-2) है।
