3x2 + 9x 3x(x + 3) -------------
You take out the common factor, x. x2 - 9x = x(x - 9)
5x2 + 9x + 13 has no real factors.
If that's -49, there is a formula for the "difference of squares." In this case, the answer is (9x + 7)(9x - 7)
The GCF is 3x.
factor out a 3x 3x(x-3)=3x2-9x
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.
x2-9x = x(x-9)
The GCF of 6x and 9x is 3x
3x2 + 9x 3x(x + 3) -------------
If that's + 49y2, the answer is (9x - 7y)(9x - 7y) or (9x - 7y)2
102 +9x +4 = 9x + 106, which is in its simplest form.
If that's + 49y2, the answer is (9x - 7y)(9x - 7y) or (9x - 7y)2
If that's + 18x + 1, the answer is (9x + 1)(9x + 1) or (9x + 1)2
Asuming you ment The Factor of x^2+9x+18 the answer is (x+3)(x+6) Asuming you ment The Factor of x^2+9x+18 the answer is (x+3)(x+6)
You take out the common factor, x. x2 - 9x = x(x - 9)
you can't
