Question

SOLVE .........(5x - 10 ) (5x + 10) = ❓​

Answer 1

Step-by-step explanation:

Here,

(5x - 10) ( 5x + 10)

According to a² - b²

(5x)² - (10)²

25x² - 100

25( x² - 4)

Answer 2

Answer:

25x^2-100

Step-by-step explanation:

5x times 5x = 25x^2

-10 times 5x = -50x

+10 times 5x = +50x

-10 x 10 = -100

so 25x^2-50x+50x-100

simplified would be 25x^2-100

as 50x +50x = 0 which cancels out.

So answer is 25x^2-100
