Solution for 63=(5+s)(7+s) equation:


Simplifying
63 = (5 + s)(7 + s)

Multiply (5 + s) * (7 + s)
63 = (5(7 + s) + s(7 + s))
63 = ((7 * 5 + s * 5) + s(7 + s))
63 = ((35 + 5s) + s(7 + s))
63 = (35 + 5s + (7 * s + s * s))
63 = (35 + 5s + (7s + s2))

Combine like terms: 5s + 7s = 12s
63 = (35 + 12s + s2)

Solving
63 = 35 + 12s + s2

Solving for variable 's'.

Combine like terms: 63 + -35 = 28
28 + -12s + -1s2 = 35 + 12s + s2 + -35 + -12s + -1s2

Reorder the terms:
28 + -12s + -1s2 = 35 + -35 + 12s + -12s + s2 + -1s2

Combine like terms: 35 + -35 = 0
28 + -12s + -1s2 = 0 + 12s + -12s + s2 + -1s2
28 + -12s + -1s2 = 12s + -12s + s2 + -1s2

Combine like terms: 12s + -12s = 0
28 + -12s + -1s2 = 0 + s2 + -1s2
28 + -12s + -1s2 = s2 + -1s2

Combine like terms: s2 + -1s2 = 0
28 + -12s + -1s2 = 0

Factor a trinomial.
(2 + -1s)(14 + s) = 0

Subproblem 1

Set the factor '(2 + -1s)' equal to zero and attempt to solve: Simplifying 2 + -1s = 0 Solving 2 + -1s = 0 Move all terms containing s to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1s = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1s = 0 + -2 -1s = 0 + -2 Combine like terms: 0 + -2 = -2 -1s = -2 Divide each side by '-1'. s = 2 Simplifying s = 2

Subproblem 2

Set the factor '(14 + s)' equal to zero and attempt to solve: Simplifying 14 + s = 0 Solving 14 + s = 0 Move all terms containing s to the left, all other terms to the right. Add '-14' to each side of the equation. 14 + -14 + s = 0 + -14 Combine like terms: 14 + -14 = 0 0 + s = 0 + -14 s = 0 + -14 Combine like terms: 0 + -14 = -14 s = -14 Simplifying s = -14

Solution

s = {2, -14}
