How to Solve Quadratic Equations

Factoring Method 

Factoring the left hand side (LHS); 

Either 

Or 

Therefore, 

Quadratic Formula 

Discriminant is; 

Therefore, we have two real solutions 

Quadratic Formula: 

Substitution the values gives 

Either 

Or 

Factoring Method 

Subtract 2 from both sides 

So the equation cannot be easily solved using the factoring method.
