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)
