Question

Which expressions represent a quadratic expression in factored form?A (x - 1)(x - 1)B5(X+9)C (x-3)(x + 2)D) x + xE (x + 4) - (x + 6)

Answer 1

A. (x - 1)(x - 1)

C. (x -3)(x + 2)

Step-by-step explanation:

A quadratic equation has the following form:

(x + a)(x + b)

So, the expressions that represent a quadratic equation are:

A. (x - 1)(x - 1)

C. (x -3)(x + 2)

Because there are 2 expressions with the form (x + c) that are multiplied.
