Solution for (s-t)*(3s+8t)= equation:


Simplifying
(s + -1t)(3s + 8t) = 0

Multiply (s + -1t) * (3s + 8t)
(s(3s + 8t) + -1t * (3s + 8t)) = 0
((3s * s + 8t * s) + -1t * (3s + 8t)) = 0

Reorder the terms:
((8st + 3s2) + -1t * (3s + 8t)) = 0
((8st + 3s2) + -1t * (3s + 8t)) = 0
(8st + 3s2 + (3s * -1t + 8t * -1t)) = 0
(8st + 3s2 + (-3st + -8t2)) = 0

Reorder the terms:
(8st + -3st + 3s2 + -8t2) = 0

Combine like terms: 8st + -3st = 5st
(5st + 3s2 + -8t2) = 0

Solving
5st + 3s2 + -8t2 = 0

Solving for variable 's'.

Factor a trinomial.
(s + -1t)(3s + 8t) = 0

Subproblem 1

Set the factor '(s + -1t)' equal to zero and attempt to solve: Simplifying s + -1t = 0 Solving s + -1t = 0 Move all terms containing s to the left, all other terms to the right. Add 't' to each side of the equation. s + -1t + t = 0 + t Combine like terms: -1t + t = 0 s + 0 = 0 + t s = 0 + t Remove the zero: s = t Simplifying s = t

Subproblem 2

Set the factor '(3s + 8t)' equal to zero and attempt to solve: Simplifying 3s + 8t = 0 Solving 3s + 8t = 0 Move all terms containing s to the left, all other terms to the right. Add '-8t' to each side of the equation. 3s + 8t + -8t = 0 + -8t Combine like terms: 8t + -8t = 0 3s + 0 = 0 + -8t 3s = 0 + -8t Remove the zero: 3s = -8t Divide each side by '3'. s = -2.666666667t Simplifying s = -2.666666667t

Solution

s = {t, -2.666666667t}
