x = ? 42 = x squared minus x
(x - 5)(x + 4)
x - 3
24
The answer to x2 - 2x - 4y2 - 4y =(x - 2y)(x - 2y - 2)
xsquared minus x minus 72
x = ? 42 = x squared minus x
x + 1
-1 is the answer. With an odd number of -1s, we end up back where we started as each multiplication only switches from positive to negative.
-3
(x - 5)(x + 4)
(x−6)(x+5)
It is: (x+5)(x-8) when factored
By factoring I get x-3 divided by x+3
(x+4)(x-7)
x(x + 3)(x - 4)
(x + 2)(x - 4)
