(2f+3)(f-4)=

Solution for (2f+3)(f-4)= equation:

Simplifying
(2f + 3)(f + -4) = 0

Reorder the terms:
(3 + 2f)(f + -4) = 0

Reorder the terms:
(3 + 2f)(-4 + f) = 0

Multiply (3 + 2f) * (-4 + f)
(3(-4 + f) + 2f * (-4 + f)) = 0
((-4 * 3 + f * 3) + 2f * (-4 + f)) = 0
((-12 + 3f) + 2f * (-4 + f)) = 0
(-12 + 3f + (-4 * 2f + f * 2f)) = 0
(-12 + 3f + (-8f + 2f2)) = 0

Combine like terms: 3f + -8f = -5f
(-12 + -5f + 2f2) = 0

Solving
-12 + -5f + 2f2 = 0

Solving for variable 'f'.

Factor a trinomial.
(-3 + -2f)(4 + -1f) = 0

Subproblem 1
Set the factor '(-3 + -2f)' equal to zero and attempt to solve:

Simplifying
-3 + -2f = 0

Solving

Add '-4' to each side of the equation.
4 + -4 + -1f = 0 + -4

Combine like terms: 4 + -4 = 0
0 + -1f = 0 + -4
-1f = 0 + -4

Combine like terms: 0 + -4 = -4
-1f = -4

Divide each side by '-1'.
f = 4

Simplifying
f = 4
Solution
f = {-1.5, 4}
