Simplify (2x-5)²- (2x+5)²

Step-by-step explanation:

$(2x-5)²- (2x+5)²$

$= [ 2x²- (2)(2x)(5) + 5² ] - [ 2x² + (2)(2x)(5) + 5² ]$

$= [ 4x² - 20x + 25 ] - [ 4x² + 20x + 25 ]$

$= 4x² - 20x + 25 - 4x² - 20x - 25$

$= - 40x$

Answer 2

(2x−5)^2 − (2x+5)^2

=4x2+−20x+25+−4x2+−20x+−25

Combine Like Terms:

=4x2+−20x+25+−4x2+−20x+−25

=(4x2+−4x2)+(−20x+−20x)+(25+−25)

=−40x
