-3(4x-8.2) < -11.98x + 14 3/4
Expand by using distributive property
-12x + 24.6 < -11.98x + 14.75
Subtract 24.6 from both sides
-12x < -11.98x - 9.85
Add both sides by -11.98x
-0.02x < - 9.85
Divide both sides by -0.02 (sign will be flipped)
x > 492.5
Hope it helps.
The concept of factoring quadratic equations simply is one of the ways to solve for the zeroes of the quadratic equation.
<h3>What is quadratic equations by factoring?</h3>
The concept of factoring quadratics is a technique which is characterized by expressing the quadratic equation ax2 + bx + c = 0 as a product of its associated linear factors as (x - f)(x - g), in which case, f and g are the roots of the quadratic equation ax2 + bx + c = 0.
Factoring is an important concept that helps express equations of any type in simpler forms The mode of operation of the factoring works such that, the polynomial is rewritten in a simpler form and consequently, expressed as a product of it's linear factors.

Answer:
- 4x^2-15x
Step-by-step explanation:
(f-g)(x) = f(x) - g(x) = - 3x^2-8x-x^2-7x = - 4x^2-15x
