Question

Select the correct answer.

Which expression represents a quadratic expression in complete factored form?
Α.
(x + 4)(x-3)
B.
(2x+4)(x+3)
C.
(x - 1)(3x-9)
D.
(x-2) + (x + 3)

Answer 1

C. (x + 4)(x − 3)

Explanation:

A quadratic expression in complete factored form can be written as the product of two linear factors, where each factor is in the form of (ax + b). The expression (x + 4)(x - 3) is in this form and can be expanded to the quadratic expression x^2 + x - 12.

Option A is a sum of two linear expressions, but it is not factored. Option B is a product of two linear expressions, but it can be simplified to the quadratic expression 3x^2 - 3x. Option D is a product of two linear expressions, but it can be simplified to the quadratic expression 2x^2 + 10x + 12.
