It is (x+9(x-2) when factored
(x - 6)(x - 3)
To factor this, find two numbers whose product is 81 and sum 18. These two numbers are therefore 9 and 9. So we can rewrite the polynomial in its factored form as follows: (k+9)(k+9), or "k plus 9 squared"
-((x + 2)(x - 9))
18 because, 5x2=10 10+8=18! Your welcome. It's not a problem at all. I love math!
(x - 3)(x + 6)
It is (x+9(x-2) when factored
It is (x+2)(x+9) when factored
x^2 + 7x -18 = (x - 2)(x + 9)
(x - 6)(x - 3)

3x2 + 33x + 54 =3(x2 + 11x + 18) = 3(x + 9)(x + 2)
It is the same as xsquared+9x+18 and when factored: (x+3)(x+6)
Yes, 18y3 + 2y2 + 1 is a polynomial; it is a cubic expression. If it were expanded to form an equation, then it would be a cubic equation (or higher), capable of solution.
(x - 2)(2x + 9)
