By factoring I get x-3 divided by x+3
722 = 72 x 72 = 5184
(x + 2)(x - 9)
-3
3x2 - 2x - 5 = (3x - 5)(x + 1) = 0 gives a solution of x = 5/3 or -1. Was that what you wanted?
x = 2.1374586088176875 x = -1.6374586088176875
x = ? 42 = x squared minus x
x^2 +9 =x^2 -9 9=-9 No solution
72 minus the root of squared minus equals 72 but you have to be smart to know that the minimum circumference s 56 there you go
x sq equalls 36 and x equalls plus or minus 6
x2 -x -12 = 0 (x+3)(x-4) = 0 Therefore, x = -3 & 4
By factoring I get x-3 divided by x+3
-22 - -22
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)
