Factor out -2: -2(x squared +11x-20). This is fully factored.

No answer in integers, nor outside the realm of imaginary numbers. Typo?

3x2 - 11x - 4 = (x-4)(3 x + 1)

(3x+1)(2x+4)

The factors are -1(2x + 1)(3x + 4)

11x + 2

3x2 - 11x - 4 = 0(3x + 1)(x - 4)x = -1/3 and 4

You have to experiment with different factors of 2, and different factors of 15. In this case, 2x2 - 11x + 15 = (2x - 5) (x - 3)

The discriminant, for what it is worth in an example such as this, is 11.

2x2 + 11x + 15 = (x + 3)(2x + 5).

-x-6-(-11x) + (-1) Remove the brackets: -x-6+11x-1 Collect and simplify like terms: 10x-7 A - - is equal to a +

-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2

11x = 8x-6.............. 11x-8x = -6................... 3x= -6 x = -2

The equation -30 times -10 plus 11X equals -29. This is a math problem.

If 6x + 10 = 11x , then x=2.
