(x-3)(x-9) = 0
(3x - y+ 2)(3x + y + 2)
30+12x = 6(5+2x)
x2+12x+5 = 3 x2+12x+5-3 = 0 x2+12x+2 = 0
6(x + 1)(x + 1)
(x-3)(x-9) = 0
(3x - y+ 2)(3x + y + 2)
30+12x = 6(5+2x)
x2+12x+5 = 3 x2+12x+5-3 = 0 x2+12x+2 = 0
6(x + 1)(x + 1)
2(x + 4)(x + 2)
(x - 8)(x - 4)
(2x - 3)(2x - 3)
(2x - 1)(6x + 5)
(-3, -5)
The answer is (2x^2+3)(4x+1)
4x(4x^2 + 3x + 1)
