You don't need to factor that; you can add them together, since they have the same variable.However, assuming you might mean 81x squared + 9x, you can take out the common factor, which is 9x.
9x+6=51 9x = 45 x= 5 9x-6=51 9x = 57 x= 6.33

9x23
-9x - 10 = 62 -9x = 72 x = -8
If you mean 9x+x then it is 10x when simplified
If you mean (9x-8y)(9x+8y) then it is 81x^2 minus 64y^2
If you mean: 7x-53 = 9x Then the solution is: x = -26.5
If you mean 4x-13x = 2, then-9x = 2-9x/-9 = 2/-9x = -2/9
If you mean 9x -7 = -115 then the value of x is -12
If you mean: 9x-2y = 7 then it is y = 4.5x-3.5
If you mean: 2x2 -9x +4 then it can be factored to (2x-1)(x-4)
9x+39
9x+39
Assuming you mean 3x - 2 = 9x - 5...3x - 2 = 9x - 53x + 3 = 9x3 = 6x0.5 = x
You don't need to factor that; you can add them together, since they have the same variable.However, assuming you might mean 81x squared + 9x, you can take out the common factor, which is 9x.
I suppose you mean, how do you factor it. 7x2 - 9x - 10 = (7x + 5)(x - 2).
