x2 + 11x + 24 You want the equation to be in the form (x + a)(x + b), where the two solutions are -a and -b.You know that...ab = 24...and...a + b = 11Note that 8 times 3 is 24, and 8 plus 3 is 11.x2 + 11x + 24 = (x + 3)(x + 8)The two answers are x = -3 and x = -8.
No. It factors to (11x - 13)(2x - 3)
The factors are -1(2x + 1)(3x + 4)
x^3 - 121x
I'm not sure this was notated correctly. As written, this is -11x plus or minus 18, which doesn't factor.
x+11x+30(x+5)(x+6)
(2x - 1)(5x + 8)
(x - 1)(2x - 9)
Factor out -2: -2(x squared +11x-20). This is fully factored.
x^3 - 121x
There's a factor pair of 30 that adds up to 11. (x + 5)(x + 6)
x2 - 11x + 24 = (x - 3)(x - 8)
No answer in integers, nor outside the realm of imaginary numbers. Typo?
6x^2 + 11x + 4 is a Quadratic Statement. It is NOT an equation, because there is no 'equals' (=). It will factor to ( 3x + 4)(2x + 1)
2x2 + 11x + 12 = 2x2 + 3x + 8x + 12 = x*(2x + 3) + 4*(2x + 3) = (2x + 3)*(x + 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)
