Difference of Squares Formula - Practice (Part1 & Part2) - 30 problems

This is an engaging practice on applying the difference of squares formula. It consists of 2 parts as each part contains two tasks. The first part is applying the formula (a - b)(a+b)=a^2 - b^2 to simplify expressions and the second part is applying the formula a^2 - b^2=(a -b)(a+b) to factorize expressions.

Detailed description:

Part 1
Task 1. Students have to apply the difference of squares formula to simplify 9 expressions (problems level 1).
Task 2. Students have to simplify 6 expressions as they will have to multiply binomials and also use the formulas for square of sum and square of difference (problems level 2).

Part 2
Task 1. Students have to factorize 9 expressions (problems level 1).
Task 2. Students will need to apply the difference of squares formula from left to right and from right to left to solve 6 equations (problems level 2). They will use the square of sum formula once and the square of difference formula also once.
