The expression x2 + 1x - 12 can be factored out as (x - 3)(x + 4)
-9
x = ? 42 = x squared minus x
it is equal to +x
I assume you wanted this factored: (x+6)(x-2)
It is x^2 -x -12 is (x+3)(x-4) when factored
(x - 12)(x + 12)
x2_12x-3 = 0 Using the formula for solving quadratics: x = 12 plus/minus sqrt (144 - (4 x 1 x -3))/2 x = 12 plus/minus (sqrt 156)/2 x = 12 + (sqrt 156)/2 = 12.25 or x = 12 - (sqrt 156)/2 = -0.25
x2 -x -12 = 0 (x+3)(x-4) = 0 Therefore, x = -3 & 4
(6 x 10-2) / (1 x 10-12) = 6 x 10(-2+12) = 6 x 1010
5/12 or (9 x 12) - (4 x 12) = (5 x 12) = 60 Nine of anything minus four of the same thing is always five of them.
x2-10x-24 = (x+2)(x-12) when factored
x >/= 12
2x - 12 > 2 + x x - 12 > 2 x > 14
It is x^2 -13x +12 = (x-1)(x-12) when factored
x - 12 = 3 Add '12' to both sides x = 3 + 12 x = 15
