Identify the factors of x2 − 4x − 12. (1 point)
(x + 4)(x − 3)
(x − 4)(x + 3)
(x − 2)(x + 6)
(x + 2)(x − 6)

D.

Step-by-step explanation:

We have been given a polynomial . We are asked to find the factors of our given polynomial.

We will use splitting the middle term format of factoring quadratic polynomial.

We need two numbers, whose product is and whose sum is . Such two numbers are  .

Factor out GCF of each group:

Therefore, factors of our given expression are and option D is the correct choice.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
