Given:
4x + 12
Factor the expression.
Solution:
In order to factor the expression, we simply must determine the greatest common factor. In our case we know that 4 is a factor of 12, hence we can factor 4 out of the equation.
= 4x + 12
= 4(x + 3)
Now we can solve the value of x by transposing 3 on the other side of the equation, thus we must take note that when transposing a number, the sign changes.
x + 3
x = -3
Final answer:
Factored form
= 4(x + 3)
x = -3
