Write the following conjugate binomial in standard form.
Like this example.
A(x + 3) (x - 3)
= x( x - 3) + 3 (x - 3)
= x^2 - 3x + 3x -9
= x^ 2 -9
I have to answer B like this but I'm not sure if you have to repeat (x+5) twice or (x-5) considering the fact that it's written like this instead.
B(x - 5 ) ( x + 5)
Like this example.
A(x + 3) (x - 3)
= x^2 - 3x + 3x -9
= x^ 2 -9
