Question

Can someone help me with this please??

Answer 1

Answer:

(x-5)*(x+5)

Step-by-step explanation:

= x^2 + 5x - 25 - 5x

= x^2 +5x - 5x -25

because +5x - 5x = 0 so

= x^2 + 0 - 25

= x^2 - 25

25 can be written as 5^2

= x^2 - 5^2

we know that a^2 - b^2 = (a-b) * (a+b)

so x^2 - 5^2

= (x-5) * (x+5)

Hope this help you :3
