Factoring Quadratic Expressions

Lesson 7 Factoring Quadratic Expressions (Special Products)

​

Multiple Choice

Match each quadratic expression given in factored form with an equivalent expression in standard form. One expression in standard form has no match.

(y+x)(y−x)

• $$121-x^2$$

• $$x^2+2xy-y^2$$

• $$y^2-x^2$$

• $$x^2-2xy+y^2$$

• $$x^2-121$$

Multiple Choice

Match each quadratic expression given in factored form with an equivalent expression in standard form. One expression in standard form has no match.
