11x + 2
2x + 9 = 6x + 1 9 - 1 = 6x - 2x 8 = 4x x = 2
Let 6x - 2x - 9 = a, where a is an arbitrary constant. Then 4x - 9 = a 4x = a+9 x = (a+9)/4
4x2 + 6x - 3 (with no remainder)
1x^2-6x+91X9 IS 9What multiplies to get 9 and adds to get -6? -3x-3So, (x-3)(x-3)
11x + 2
2x + 9 = 6x + 1 9 - 1 = 6x - 2x 8 = 4x x = 2
6x - 9 + 2x + 1 = 8x -8
8x2 + 6x - 9 = 8x2 + 12x - 6x - 9 = 4x(2x + 3) - 3(2x + 3) = (2x + 3)(4x - 3)
(4x - 3)(2x + 3)
With great difficulty not knowing if 6x and 27 are plus or minus
0.2x + 6x - 1 = -9 6.2x = -8 x = -1.2903225806451612903225806451613
Let 6x - 2x - 9 = a, where a is an arbitrary constant. Then 4x - 9 = a 4x = a+9 x = (a+9)/4
{-1,7}
4x2 + 6x - 3 (with no remainder)
3x + 6x +1 = 10 9x = 10 - 1 9x = 9 x = 1
6x + 9 + 2x = 8x + 9
