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

y^{2}-x^{2}
121-x{2}
x^{2}-121
x^{2}-2xy+y^{2}

Both (x-3)(x+3) and (3-x)(3+x) contain a sum and a difference and have only 3 and in each factor.

If each expression is rewritten in standard form, will the two expressions be the same? Explain or show your reasoning.

What are the solutions to the equation (x-a)(x+b)=0 ?

Create a diagram to show that (x-3)(x-7) is equivalent to x^{2}-10x+21.

Select all the expressions that are equivalent to 8-x.

Which statement is true about the two populations?
