The GCF is 9.
2x2 + 17x - 9 = 2x2 + 18x - x - 9 = 2x(x + 9) - 1(x + 9) = (2x - 1)(x + 9)
9(x - 3y)
(2x+3)(x+3)
factor out a 3x 3x(x-3)=3x2-9x
2x2 - 9x = 18 2x2 - 9x -18 = 0 (2x - 18)(x + 9) x= -9 and 9
2x2 + 10 - 9x = 0 or 2x2 - 9x + 10 = 0 So (x - 2)*(2x - 5) = 0
2x2 - 9x + 4 = (2x - 1)(x - 4)
(2x + 1)(x + 4)
2x2+9x+9 = (2x+3)(x+3) when factored
2x2 - 9x + 10 = 2x2 - 4x - 5x + 10 = 2x(x - 2) - 5(x - 2) = (x - 2)(2x - 5)
2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0
I hope you mean x3+2x2-9x+18. Treat the equation like two equations: x3+2x2 and 9x+18. Factor out x2 from the first equation, so x2(x+2). Factor out 9 from the second equation, so 9(x+2). Now, the whole equation. x2(x+2)-9(x+2). Factor out (x+2), so (x+2)(x2-9). (x2-9) factors into (x+3)(x-3). So, (x+2)(x+3)(x-3) is the complete factorization. Hope this helps.
If you mean: 2x2 -9x +4 then it can be factored to (2x-1)(x-4)
x2-9x = x(x-9)
you can't
The factorisation is as follows: 2x2 + 7x - 9 = (x - 1)(2x + 9).
