randRange(2, 9) randRange(1, 9) A * A -B * B

Factor the expression below completely. All coefficients should be integers.

`SQUAREx^2` `+-` `abs(CONSTANT)`

(Ax + B)(Ax - B)

The expression is of the form `\pink{a^2} - \blue{b^2}`, which is a difference of two squares so we can factor it as `(\pink{a} + \blue{b})(\pink{a} - \blue{b})`.

$("#question-x").addClass("hint_pink"); $("#question-c").addClass("hint_blue");

What are the values of `\pink{a}` and `\blue{b}`?

`\qquad \pink{a = \sqrt{SQUAREx^2} = Ax}`

`\qquad \blue{b = \sqrt{B * B} = B}`

Use the values we found for `\pink{a}` and `\blue{b}` to complete the factored expression, `(\pink{a} + \blue{b})(\pink{a} - \blue{b})`.

So we can factor the expression as: `(\pink{Ax} + \blue{B})(\pink{Ax} - \blue{B})`
