(3x + 8)(3x - 8)
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
(9x2 + 7)(9x2 - 7) = 81x4 - 49
That factors to 3x(3x - 1)
This is a difference of two squares, which factorises to: (3x - 4y)(3x + 4y)
x2-9x can be factored by taking x out of each term x(x-9)
(3x + 8)(3x - 8)
(9x + 8)(9x - 8)
(x + 3)(3x - 2)
x2-9x+8=0 has two solutions:x = 8x = 1
(x + 12)(x - 3)
9x2-9x-10 = (3x+2)(3x-5) when factored
(x + 2)(3x - 1)(3x + 1)
9x2 - 18x + 99(x2 - 2x + 1)==========
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
(9x2 + 7)(9x2 - 7) = 81x4 - 49
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
