(x + 3)(3x - 2)
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
9x2 - 18x + 99(x2 - 2x + 1)==========
Assuming it's a plus sign, that factors to (2x + 1)(x + 4)
(9x + 8)(9x - 8)
(x + 3)(3x - 2)
(x + 12)(x - 3)
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
9x2 - 18x + 99(x2 - 2x + 1)==========
(x + 2)(3x - 1)(3x + 1)
x2-9x can be factored by taking x out of each term x(x-9)
Assuming it's a plus sign, that factors to (2x + 1)(x + 4)
(3x + 8)(3x - 8)
(9x + 8)(9x - 8)
x2 - 9x + 20 = (x - 4)( x - 5)
It is a difference of squares. 9x^2-49=(3x+7)(3x-7)
