Answer:
or 
Step-by-step explanation:
When given the following equation,

One must follow the order of operations to solve the equation and get a valid result. The order of operations states the following,
1. Parenthesis
2. Exponents
3. Multiplication/ Division
4. Addition/ Subtraction.
Normally, one would combine the terms in the parenthesis, but since they are unlike terms, one will have to undo the exponents first. Expand the binomial.

Now distribute, multiply every term inside the parenthesis by the term outside,

Simplify,



Inverse operations,

To simplify the equation, divide all terms by (2).

Factor, rewrite the quadratic equation as a product of linear equations,

Solve using the zero product property. The zero product property states that any number times zero equals zero,
