(p(x)=6x-2-x+3) से (r(x)=2x-2+5x-8) घटाने पर क्या मिलेगा?
What is obtained when (r(x)=2x-2+5x-8) is subtracted from (p(x)=6x-2-x+3)?
Explanation opens after your attempt
A. \(4x^2-6x+11\)
Concept
(p(x)-r(x)=6x-2-x+3-\(2x^2+5x-8\)=4x-2-6x+11). Change all signs inside the bracket while subtracting.
Why this answer is correct
The correct answer is A. \(4x^2-6x+11\). (p(x)-r(x)=6x-2-x+3-\(2x^2+5x-8\)=4x-2-6x+11). Change all signs inside the bracket while subtracting.
Exam Tip
(p(x)-r(x)=6x-2-x+3-\(2x^2+5x-8\)=4x-2-6x+11)। घटाते समय कोष्ठक के सभी संकेत बदलें।
