(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
2(3x + 4) + 5x - 2
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
3x-4=5x+6 gives: 2x=-10 which gives x=-5
if you meant 5x+9=3*15 then, 5x = 36, x = 7.2 if you meant 5x+9=3x+15 then, 2x = 6, x = 3
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)
-15x2+5x=-5x(3x-1)
The given expression can be simplified to: 8x squared +9
5x(3x + 1)
(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
3x2 + 5x + 2 is a quadratic expression that can be factored as follows: 3x2 + 5x + 2 = 3x2 + 3x + 2x + 2 = 3x(x + 1) + 2(x + 1) = (3x + 2)(x + 1)
It is a quadratic equation in the variable x.
3x3+15x2+18x = 3x(x2+5x+6) = 3x(x+2)(x+3)
6x2 + 5x - 6 is factored out to (2x + 3)(3x - 2).
