2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
2x2 + 10 - 9x = 0 or 2x2 - 9x + 10 = 0 So (x - 2)*(2x - 5) = 0
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
2x2 - 9x + 4 = (2x - 1)(x - 4)
2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
2x2 + 10 - 9x = 0 or 2x2 - 9x + 10 = 0 So (x - 2)*(2x - 5) = 0
2x2 - 9x = 18 2x2 - 9x -18 = 0 (2x - 18)(x + 9) x= -9 and 9
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
2x2 - 9x + 4 = (2x - 1)(x - 4)
(2x + 1)(x + 4)
2x2 + 9x + 10
2x2+9x+9 = (2x+3)(x+3) when factored
2x2-9x+4 = (2x-1)(x-4) when factored
it equals 13X.
The slope is 0.
