Factoring difference of squares 3

The  exercise appears under the Algebra I Math Mission. This exercise continues practice with the difference of squares factoring formula.

Types of Problems
There is one type of problem in this exercise:


 * 1) Factor the quadratic: This problem provides a polynomial that is quadratic and in the form of difference of squares with a leading coefficient that might not be one. Also, the student may need to pull out a GCF before applying the difference of squares formula. The student is expected to find the correct factoring and write it in the space provided.Facdifsqu3-1.png

Strategies
Knowledge of the difference of squares factoring technique is highly recommended for accuracy and efficiency on this exercise.


 * 1) The difference of squares formula says $$ a^2-b^2=(a+b)(a-b)$$.
 * 2) This problem generally requires the factoring out of a greatest common factor before factoring by difference of squares.
 * 3) The answer box will automatically insert a closing parentheses when the user inputs a beginning parentheses.

Real-life Applications

 * 1) Any strength or practice with polynomials assists in the calculus for finding zeroes and also for power series of general functions.
