Solution for (s+10)(s-8)= equation:


Simplifying
(s + 10)(s + -8) = 0

Reorder the terms:
(10 + s)(s + -8) = 0

Reorder the terms:
(10 + s)(-8 + s) = 0

Multiply (10 + s) * (-8 + s)
(10(-8 + s) + s(-8 + s)) = 0
((-8 * 10 + s * 10) + s(-8 + s)) = 0
((-80 + 10s) + s(-8 + s)) = 0
(-80 + 10s + (-8 * s + s * s)) = 0
(-80 + 10s + (-8s + s2)) = 0

Combine like terms: 10s + -8s = 2s
(-80 + 2s + s2) = 0

Solving
-80 + 2s + s2 = 0

Solving for variable 's'.
