Question

(2x+5)2-(2x-5)2=40x​

Answer 1

=( 2x + 5 )2-(2x-5)2=40x

=4x+10-4x+10= 40x

= x+20=40x

=x=20

Answer 2

Answer:

yes the answer is right

Step-by-step explanation:

2x + 5x5 - 40x = 2x - 5x5

2x + 25 - 40x = 2x - 25

25 - 40x - 2x = 2x - 25

25 - x(40-2)= 2x - 25

25 - 38x = 2x - 25

= 2x + 38x - 25 -25

=x(2 + 38) -0

=40x
