G. Factoring
III. Factoring by Grouping
Step 1: Factor out a GCF if possible.
Step 2: Group the first two terms together and the last two terms together.
Step 3: Factor out the GCF from each of the two groups.
Step 4: The factors inside of the parenthesis should be exactly the same. The matching binomials are your first factor, the coefficients of the parentheses form your second binomial..
Step 5: Determine if the remaining factors can be factored any further.
Example 1 β Factor:
Step 1: Decide if the four terms have anything in common, called the greatest common factor or GCF. If so, factor out the GCF. Do not forget to include the GCF as part of your final answer. In this case, the four terms only have a 1 in common which is of no help.
Step 2: Create smaller groups within the problem, usually done by grouping the first two terms together and the last two terms together.
Step 3: Factor out the GCF from each of the two groups. In this problem, the signs in front of the 5x2 and the 15 are different, so you need to factor out a positive 3.
Step 4: Notice that what is inside the parentheses is a perfect match. The one thing that the two groups have in common is (x β 5), so you can factor out (x β 5) leaving the following:
Step 5: Determine if any of the remaining factors can be factored further. In this case they cannot so the final answer is:

H. Solving Quadratic Equations
Quadratic Equation β An equation where the variable is raised to the 2nd power.
2 0ax bx c (standard form)
x represents an unknown variable, and parameters a, b, and c are the coefficients of the equation.
There are several methods of solving quadratic equations. These include solving by:
I. factoring (if possible β Zero Product Property)
II. square root property (use when there is no middle term)
III. using the quadratic formula (always works)
I. Solving by Factoring (using the zero-product property)
Step 1: Write the equation in standard form.
Step 2: Use factoring strategies to factor the problem.
Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.
Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.
Example β Solve: 18x2 β 3x = 6
Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.
Step 2: Use a factoring strategies to factor the problem.
Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.
Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.
II. Solving by Using the Square Root Property
Step 1: Isolate the perfect square.
Step 2: Take the square root of each side. Donβt forget the Β±.
Examples:
III. Quadratic Formula
Step 1: Make sure the equation is in Standard form.
Step 2: Identify a, b, and c in the equation. Step 3: Substitute the values of a, b, and c into the quadratic formula. Be careful with parentheses and negative numbers. Step 4: Simplify this expression to determine the values for x.
