Answer:
2+5(x+3)- (2x-7)(x+2)
7(x+3)- (3x+4x-7x-14)
(7x+21)-(7x-7x-14)
(7x+21)-(14)
7x+21-14
=7x+7
Answer:
4x+7-2x²
Step-by-step explanation:
2+5(x+3)- (2x-7)(x+2)
First we have to divide them into 2 parts
part 1= 2+5(x+3)
part 2= (2x-7)(x+2)
Then, we have to solve them in parts
First part1= 2+5(x+3)
=2(x+3)+5(x+3)
=2x+6+5x+15
=2x+5x+15+6
=7x+21
OR SIMPLE WAY OF DOING PART1
2+5(x+3)
=7(x+3)
=7x+21
Then part2= (2x-7)(x+2)
=2x(x+2)-7(x+2)
=2x²+4x-7x-14
=2x²-3x-14
THEN JUST SIMPLIFY
7x+21-2x²-3x-14
=7x-3x+21-14-2x²
=4x+7-2x²
