s*s=(s+3)(s-2)

Solution for s*s=(s+3)(s-2) equation:

Simplifying
s * s = (s + 3)(s + -2)

Multiply s * s
s2 = (s + 3)(s + -2)

Reorder the terms:
s2 = (3 + s)(s + -2)

Reorder the terms:
s2 = (3 + s)(-2 + s)

Multiply (3 + s) * (-2 + s)
s2 = (3(-2 + s) + s(-2 + s))
s2 = ((-2 * 3 + s * 3) + s(-2 + s))
s2 = ((-6 + 3s) + s(-2 + s))
s2 = (-6 + 3s + (-2 * s + s * s))
s2 = (-6 + 3s + (-2s + s2))

Combine like terms: 3s + -2s = 1s
s2 = (-6 + 1s + s2)

Add '-1s2' to each side of the equation.
s2 + -1s2 = -6 + 1s + s2 + -1s2

Combine like terms: s2 + -1s2 = 0
0 = -6 + 1s + s2 + -1s2

Combine like terms: s2 + -1s2 = 0
0 = -6 + 1s + 0
0 = -6 + 1s

Solving
0 = -6 + 1s

Solving for variable 's'.

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

Add '-1s' to each side of the equation.
0 + -1s = -6 + 1s + -1s
Remove the zero:
-1s = -6 + 1s + -1s

Combine like terms: 1s + -1s = 0
-1s = -6 + 0
-1s = -6

Divide each side by '-1'.
s = 6

Simplifying
s = 6
