2x2 - 9x + 10 = 2x2 - 4x - 5x + 10 = 2x(x - 2) - 5(x - 2) = (x - 2)(2x - 5)
(2x+3)(x+3)
2x2+9x+9 = (2x+3)(x+3) when factored
2x2-9x+4 = (2x-1)(x-4) when factored
(2x+3)(x+3)
Assuming it's a plus sign, that factors to (2x + 1)(x + 4)
10 + 9x
7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
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)
2x + ? = 9x9x - 2x = 7xso...2x + 7x = 9x
