Answer:
x=0 , x=-3
Step-by-step explanation:
Apply all exponent rules:
= 
×
= 
Rewrite equation with 
× + 
- 28 = 0
Solve for u to give :
u = 1, u = 1/27
Substitute back u = , solve for x :
= 1 , x= 0
, x= -3
x=0 , x=-3
Substituting x back into original equation verifies our answers

Answer:
7x² + x – 2
Step-by-step explanation:
(4x² + 3) – (–3x² – x + 5)
First, distribute the minus sign to eliminate the parentheses (negative terms become positive and vice versa):
4x² + 3 + 3x² + x – 5
Then, combine like terms:
7x² + x – 2
