Solution for solve(X+4)(X-4)=9 equation: 


Simplifying
solve(X + 4)(X + -4) = 9

Reorder the terms:
elosv(4 + X)(X + -4) = 9

Reorder the terms:
elosv(4 + X)(-4 + X) = 9

Multiply (4 + X) * (-4 + X)
elosv(4(-4 + X) + X(-4 + X)) = 9
elosv((-4 * 4 + X * 4) + X(-4 + X)) = 9
elosv((-16 + 4X) + X(-4 + X)) = 9
elosv(-16 + 4X + (-4 * X + X * X)) = 9
elosv(-16 + 4X + (-4X + X2)) = 9

Combine like terms: 4X + -4X = 0
elosv(-16 + 0 + X2) = 9
elosv(-16 + X2) = 9
(-16 * elosv + X2 * elosv) = 9
(-16elosv + elosvX2) = 9

Solving
-16elosv + elosvX2 = 9

Solving for variable 'e'.

Move all terms containing e to the left, all other terms to the right.

Reorder the terms:
-9 + -16elosv + elosvX2 = 9 + -9
