9x - 3(x + 13y) = 9x - 3x - 39y = 6x - 39y = 3(2x - 13y)
x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0
2x^3-3x^2-11x+7x+32x^2-9x+16 R -41x+3 l 2x^3-3x^2-11x+7-(2x^3+6x^2)-9x^2-11x+7-(-9x^2-27x)16x+7-(16x+48)-412x^2-9x+16-[41/(x+3)]
the answer is (3x-2)(9x squared+6x+4)
Assuming it's a plus sign, that factors to (2x + 1)(x + 4)
2x2+9x+9 = (2x+3)(x+3) when factored
2x2-9x+4 = (2x-1)(x-4) when factored
(2x+3)(x+3)
If you mean: 2x^2 +9x +7 then it is (2x+7)(x+1) when factored
Use the quadratic formula. x = -4.265564 or -0.234436
3(2x - 3)(x + 3)
2x2 - 9x + 10 = 2x2 - 4x - 5x + 10 = 2x(x - 2) - 5(x - 2) = (x - 2)(2x - 5)
2x + ? = 9x9x - 2x = 7xso...2x + 7x = 9x
(9x)2 +9x/(45x)2 +81= 9+9x/86
(x + 3)(3x - 2)
9x2 - 18x + 99(x2 - 2x + 1)==========
