x2-10x-24 = (x+2)(x-12) when factored
x2+5x-24=0(x+8)(x-3)=0x=-8 x=3
(x + 2)(x - 12)
21/24 - 4/24 = 17/24
Factors that are multiples of 3 and factors of 24? factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24. only 3, 6, 12, and 24 are multiples of 3.
-24
2x+8x-2=22 10x-2=22 10x+2=+2 10x=24 10/10=24/10 x=2.4
3x2 + 10x - 8The auxiliary equation is 3x2 + 10x - 24 [because 8*3 = 24] Two factors of -24 which sum to 10 are 12 and -2. So the factorisation of the auxillary is (3x + 12)*(3x - 2) = 3*(x + 4)*(3x - 2) Dividing by the 3 used to create the auxiliary gives the solution as (x + 4)*(3x - 2).
3x2 -14x -24 can be factored as (3x + 4)(x - 6).
It is: (2x+3)(3x-8) when factored
The equation x2 - 5x - 24 = 0 has the two solutions 8 and -3 for x.
x^2 - 10x + 24 You're looking for two factors of 24 that equal 10 (x - 6)(x - 4)
(x - 12)(x + 2)
24
2y2 - 2y - 24 has the factors (2y + 6) and (y - 4) There is a formula, but I always use trial and error. The factors of the non-x element need to be such that they can be added to give the middle element. So when you get 24, then you need to be looking at 2,12 - 3,8 - 4,6 When both the second and third element are minus values then there is a plus and a minus in the factors.
-8x+24 {This answer may be wrong: I think the question was intended to read, "Factor x2 - 10x + 24?" If so, the factors are (x - 6) and (x - 4)}
7x+6 = -3x-24 7x+3x = -24-6 10x = -30 x = -3
82 / 2 = 64/2 = 32 - 8 = 24 - 3 = 21
