(x + 2)(x - 4)
x(x - 2)
It is impossible but if it were x squared plus 2x minus 15 the equation would be (x+5) (x-3) with x being equal to either -5 or 3. If the original problem was x squared minus 2x minus 15 the equation would be (x-5)(x+3) and x would be equal to either 5 or -3
x^2(1 - x)(1 + x)
x2 - 3x - 40 = (x - 8) (x + 5)
(x - 5)(x + 4)
x2 - x = 20 x = 5
x = ? 42 = x squared minus x
By factoring I get x-3 divided by x+3
x2+x-380 = (x+20)(x-19) when factored
(x−6)(x+5)
xsquared minus x minus 72
-22 - -22
It is: (x+5)(x-8) when factored
x2 - 9x + 20 = (x - 4)( x - 5)
x + 1
(x+4)(x-7)
