(x + 9)(x − 9)<--- answer (x − 9)(x − 9) (x + 3)(x − 27) Prime Which polynomial is a difference of two squares? x2 − 16 x2 + 16 x2 − 8 x2 + 8<--- answer Factor completely: 12x3y + 6x2y2 − 9xy3 3x2y(4x2 + 2xy − 3) 3xy(4x + 2xy − 3y2) 3xy(4x2 + 2xy − 3y2)<----- answer 3x2y(4x3y − 2x2y2 − 3xy3)
3 should be x^2-16 other than that you're good
8 is not square of anything is it? where 16 = 4^2
