xsquared minus x minus 72
By factoring I get x-3 divided by x+3
(x + 2)(x - 9)
722 = 72 x 72 = 5184
-3
0x-x=0
x = 2.1374586088176875 x = -1.6374586088176875
x = ? 42 = x squared minus x
x^2 +9 =x^2 -9 9=-9 No solution
x sq equalls 36 and x equalls plus or minus 6
By factoring I get x-3 divided by x+3
-22 - -22
x2 -x -12 = 0 (x+3)(x-4) = 0 Therefore, x = -3 & 4
Find factors of -99 which sum to -2. Solution appears to be 9 and -11 (x + 9)(x - 11)
{-1,7}
(x-2)(x-4) = 0 x = 2 or x = 4
(x - 5)(x + 4)
(x−6)(x+5)
