Answer:
7x + 6 = - 48
Step-by-step explanation:
Given
x + 
= - 6
Multiply through by 8 ( the LCM of 8 and 4 ) to clear the fractions
7x + 6 = - 48 ← same equation without fractions
The answers are:
\sqrt{3}-3 ------> (g+f)(2)
0 ------> (f/g)(-1)
-3(sqrt)(3) ------> (gxf)(2)
(sqrt)(15) ------> (g-f)(-1)
F(x) = 9x² - 54x - 19 = 9x² - 57x + 3x - 19 = 3x(3x - 19) + 1(3x - 19)
= (3x - 19)(3x + 1)
f(x) = 0 if 3x - 19 =0 or 3x + 1 = 0
3x = 19 or 3x = -1
x = 19/3 or x = -1/3
