randRange(2, 9) -A * A

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

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

(x + A)(x - A)

The expression is in 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{x^2} = x}`

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

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{x} + \blue{A})(\pink{x} - \blue{A})`
