By factoring I get x-3 divided by x+3
Your question does not make sense. It would probably be interpreted as a + = ++a ---a
7x2 -4x -5x2 +2x = 2x2 -2x

The centre is (-5, 3)
X=1
You have to put your heart into it!
x^(2) + 8x + 8y +32 = 0 Then -8y = x^(2) + 8x + 32 y = (-x^(2)/8) - x - 4 In standard parabolic form. The coefficient of x^(2) is '-1/8' . It will be an 'umbrella' shaped parabola.
7(3y-2)-(-4y+9)
{-1,7}
X=-3
x = -28 / -11^2
(x, y) = (-3, -3) or (3, 3)
