Factoring difference of squares: x2−y2
Basic Concepts: Multiplying binomial by binomial, Factoring perfect square trinomials: (a+b)2=a2+2ab+b2 or (a−b)2=a2−2ab+b2, Find the difference of squares: (a−b)(a+b)=(a2−b2)
Related Concepts: Completing the square, Converting from general to vertex form by completing the square, Solving quadratic equations by factoring, Solving quadratic equations by completing the square
