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.
(x−6)(x+5)
(x+4)(x-7)
x(x + 3)(x - 4)
xsquared minus x minus 72
x = ? 42 = x squared minus x
it is equal to +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)
