Solution for (f+12)(f-15)=0 equation:


Simplifying
(f + 12)(f + -15) = 0

Reorder the terms:
(12 + f)(f + -15) = 0

Reorder the terms:
(12 + f)(-15 + f) = 0

Multiply (12 + f) * (-15 + f)
(12(-15 + f) + f(-15 + f)) = 0
((-15 * 12 + f * 12) + f(-15 + f)) = 0
((-180 + 12f) + f(-15 + f)) = 0
(-180 + 12f + (-15 * f + f * f)) = 0
(-180 + 12f + (-15f + f2)) = 0

Combine like terms: 12f + -15f = -3f
(-180 + -3f + f2) = 0

Solving
-180 + -3f + f2 = 0

Solving for variable 'f'.

Factor a trinomial.

Subproblem 1

Set the factor '(-12 + -1f)' equal to zero and attempt to solve: Simplifying -12 + -1f = 0 Solving -12 + -1f = 0 Move all terms containing f to the left, all other terms to the right. Add '12' to each side of the equation. -12 + 12 + -1f = 0 + 12 Combine like terms: -12 + 12 = 0 0 + -1f = 0 + 12 -1f = 0 + 12 Combine like terms: 0 + 12 = 12 -1f = 12 Divide each side by '-1'. f = -12 Simplifying f = -12

Subproblem 2

Set the factor '(15 + -1f)' equal to zero and attempt to solve: Simplifying 15 + -1f = 0 Solving 15 + -1f = 0 Move all terms containing f to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + -15 + -1f = 0 + -15 Combine like terms: 15 + -15 = 0 0 + -1f = 0 + -15 -1f = 0 + -15 Combine like terms: 0 + -15 = -15 -1f = -15 Divide each side by '-1'. f = 15 Simplifying f = 15

Solution

f = {-12, 15}
