Given the quadratic equation:
( x + 3 )^2
Solve for x.
Solution:
In order to solve for x, we simply need to equate x + 3 to 0.
x + 3 = 0
Solve for x, by simply transposing 3 on the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
x = 3
Final answer
x = 3
