Answer 1

x (x-5) 5( x-5)

(x×x)- (x× 5) + ( 5× x) - ( 5×5)

x squared - 5x + 5x -25

x squared -5

Answer 2

To multiply out (x - 5) (x - 5), we can use the distributive property twice:

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

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

= x^2 - 10x + 25

Therefore, (x - 5) (x - 5) simplifies to x^2 - 10x + 25.
