Answer:
Step-by-step explanation:

Could you confirm to me that this is in fact the problem? Do not report. I will edit this answer once you answer my question.
x ≠ - 4, 3
the denominator of the fraction cannot equal zero as this would make the fraction undefined. Equating the denominator to zero and solving gives the values that x cannot be
solve x² + x - 12 = 0
(x + 4)(x - 3) = 0
equate each factor to zero abd solve for x
x + 4 = 0 ⇒ x = - 4
x - 3 = 0 ⇒ x = 3
restrictions on x are : x ≠ - 4, 3
The solution of inequality
is f < 132
<em><u>Solution:</u></em>
Given that we have to find the solution of inequality
These things do not affect the direction of the inequality:
Add (or subtract) a number from both sides.
Multiply (or divide) both sides by a positive number.
Simplify the sides
<em><u>Given inequality is:</u></em>

Add 19 to both sides of equation

Multiply both the sides of inequality by 2

Thus the solution to given inequality is f < 132
