4x2-4x-120 = (2x+10)(2x-12) when factored
false!
It is; (2x+4)^2.
64
True
(2x - 5)(2x - 5)
4x2-4x-120 = (2x+10)(2x-12) when factored
Dividing all terms by 4 gives: x2-x-30 = (x-6)(x+5) when factored
The quadratic 4x2+24x+11 = (2x+1)(2x+11)
X3 - 4X2 - 45XX(X2 - 4X - 45)=============X is only common factor here.
It is: 4x2-7x-15 when factored is (4x+5)(x-3)
(3x - y)(3x - 5y) and (2x + 1)(2x + 11)
4x2-7x-15 = (4x+5)(x-3) when factored
A factor of a perfect square trinomial is eithera number that is a factor of each term of the trinomial,a binomial that is a factor of the trinomial, ora product of the above two.For example, consider 4x2 + 8x + 4It has the factors2 or 4,(x + 1) or2x+2 = 2*(x+1) or 4x+4 = 4*(x+1)
(4x + 5)(x - 3)
4x2-7x-15 (4x+5)(x-3)
