How do you factor 2x2 11x 14'?
Well, well, well, look who's trying to factor a quadratic equation! To factor 2x^2 + 11x + 14, you need to find two numbers that multiply to 28 (2*14) and add up to 11. Those numbers are 2 and 14. So, the factored form is (2x + 7)(x + 2). Voila!
Is 22x squared - 59x plus 39 a prime polynomial?
No. It factors to (11x - 13)(2x - 3)

What does 5(x 1)- 8x-4(2x-1)?
5x + 5 - 8x - 8x + 4 = 9 - 11x
Can you factor x2 plus 11x plus 18?
x2 + 11x + 18 (x + 9)(x + 2) CHECK: x2 + 9x + 2x + 18 x2 + 11x + 18 SET EACH EQUAL TO ZERO: x + 9 = 0 x = -9 x + 2 = 0 x = -2 NOW YOU ARE DONE: Solution set: {-9, -2}
