\huge\boxed{\fcolorbox{black}{pink}{ANSWER..}}

(3x²−2x+5)+(x²+4x−7)−1(2x²−5x−2)

(3x²−2x+5)+(x²+4x−7)−2x²+5x+2

Eliminate redundant parentheses

(3x²−2x+5)+(x²+4x−7)−2x²+5x+2

3x²−2x+5+x²+4x−7−2x²+5x+2

Add the numbers

3x²−2x+5+x²+4x−7−2x²+5x+2

3x²−2x+0+x²+4x−2x²+5x

Add zero

3x²−2x+0+x²+4x−2x²+5x

3x²−2x+2+4x−2x²+5x

Combine like terms

3x2−2x+x²+4x−2x²+5x

2x²−2x+4x+5x

2x²+7x
