Solution for (s-1)(s-8)=0 equation:


Simplifying
(s + -1)(s + -8) = 0

Reorder the terms:
(-1 + s)(s + -8) = 0

Reorder the terms:
(-1 + s)(-8 + s) = 0

Multiply (-1 + s) * (-8 + s)
(-1(-8 + s) + s(-8 + s)) = 0
((-8 * -1 + s * -1) + s(-8 + s)) = 0
((8 + -1s) + s(-8 + s)) = 0
(8 + -1s + (-8 * s + s * s)) = 0
(8 + -1s + (-8s + s2)) = 0

Combine like terms: -1s + -8s = -9s
(8 + -9s + s2) = 0

Solving
8 + -9s + s2 = 0

Solving for variable 's'.
