Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*(-2*x+7)-(24)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
4 • (7 - 2x) - 24 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
4 - 8x = -4 • (2x - 1)
Equation at the end of step 3 :
-4 • (2x - 1) = 0
Step 4 :
Equations which are never true :
4.1 Solve : -4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : 2x-1 = 0
Add 1 to both sides of the equation :
2x = 1
Divide both sides of the equation by 2:
x = 1/2
Answer: 8x^2 -2
Explanation:
Think about it like your pluging in a number for x, like g(1) or g(x+1), but plug in the equation for f(x)
g(f(x))= -(-8x^2 -5) -7
=8x^2 +5 -7
=8x^2 -2
