How do you factor 2x2 11x 14'?
If that's +11x + 14, the answer is (x + 2)(2x + 7)
Is 22x squared - 59x plus 39 a prime polynomial?
No. It factors to (11x - 13)(2x - 3)
How would you factor -6x squared minus 11x minus 4?
The factors are -1(2x + 1)(3x + 4)
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}
2x square plus 11x plus 5 equals?
The given expression is a quadratic equation. To find its solutions, we can either factor the equation or use the quadratic formula. However, without an equation to solve or any context, it is not possible to provide a numeric answer.
What is the quadratic formula for x2 - 2x - 3 equals 0?
(x - 3)(x + 1)
Can 5x2 plus 2x-4 equals 2x2 be solved using the quadratic formula?
Yes
What is 2x cubed plus 11x squared equals 6x?
2X^3 + 11X^2 = 6X 2X^3 + 11X^2 - 6X = 0 factor out an X X(2X^2 + 11X - 6) = 0 Now, for that quadratic equation I always go quadratic formula. Discriminant looks good for two real roots. X = -b (+/- ) sqrt(b^2-4ac)/2a a = 2 b = 11 c = - 6 X = - 11 (+/-) sqrt[11^2 - 4(2)(-6)]/2(2) X = - 11 (+/-) sqrt(169)/4 X = [- 11 (+/-) 13]/4 X = 0 X = 1/2 X = - 6
