Which expressions represent a quadratic expression in factored form?

(x − 1)(x − 1)
5(x + 9)
(x + 4) − (x + 6)
(x − 3)(x + 2)
x2 + 8x

Respuesta :

Answer:

(x-1)(x-1) and (x-3)(x+2)

Step-by-step explanation:

The quadratic equations in factored form are (x − 1)(x − 1) and (x − 3)(x + 2). Then the correct options are A and D.

What is a quadratic equation?

It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

From the given options the two correct quadratic equations are (x − 1)(x − 1) and (x − 3)(x + 2) because it will give two values of x. Also if the factors are converted into the standard form it will have a degree of two.

Hence, the correct options are A and D.
