9x2 - 18x + 99(x2 - 2x + 1)==========
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
9x squared-15x squared = -6
x = -2/3,7/6
9x2 - 18x + 99(x2 - 2x + 1)==========
If: 3 -18x^2 = 25x then 3 -18x^2 -25x = 0 When factored: (9x-1)(-2x-3) = 0Solutions: x = 1/9 or x = -3/2
If that's + 18x + 1, the answer is (9x + 1)(9x + 1) or (9x + 1)2
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
(x + 2)(3x - 1)(3x + 1)
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
9x squared-15x squared = -6
(9x - 1)(9x - 1)
It is equal to -18x^2 +9x
For any value of x, 18x divided by 2 is always 9x.
x = ±2
