2x + 9x simplified would be 11x
2x2+9x+9 = (2x+3)(x+3) when factored
2x2-9x+4 = (2x-1)(x-4) when factored
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
You can solve this as a quadratic (it's degree is 2). 9x^2+2x=7 9x^2+2x-7=0 (Hey, a quadratic!) (9x-7)(x+1)=0 Thus, the solutions for x to this problem are -1, and 7/9.

(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)
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
You can solve this as a quadratic (it's degree is 2). 9x^2+2x=7 9x^2+2x-7=0 (Hey, a quadratic!) (9x-7)(x+1)=0 Thus, the solutions for x to this problem are -1, and 7/9.
Assuming it's a plus sign, that factors to (2x + 1)(x + 4)
2x+3=9x 3=9x-2x 3=7x x=3/7
If you mean: 2x^2 +9x +7 then it is (2x+7)(x+1) when factored
3(2x - 3)(x + 3)
2x2 - 9x + 10 = 2x2 - 4x - 5x + 10 = 2x(x - 2) - 5(x - 2) = (x - 2)(2x - 5)
