A = 2
Answer:
Step by step solution :
STEP
1
:
Equation at the end of step 1
(6a • (a + 3)) - (2a • (3a + 5) + 16) = 0
STEP
2
:
Equation at the end of step 2
6a • (a + 3) - (6a2 + 10a + 16) = 0
STEP
3
:
STEP
4
:
Pulling out like terms
4.1 Pull out like factors :
8a - 16 = 8 • (a - 2)
Equation at the end of step
4
:
8 • (a - 2) = 0
STEP
5
:
Equations which are never true:
5.1 Solve : 8 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
5.2 Solve : a-2 = 0
Add 2 to both sides of the equation :
a = 2
One solution was found :
a = 2
