Solving Equations Containing Two Radicals

Question 3 • IC Pre-Cal - Deering

The result of setting the quadratic equation equal to 0 is x2 – 2x – 8 = 0.Choose the correct factorization of this equation.

Answer
A
(x – 4) (x – 2) = 0
B
(x – 4) (x + 2) = 0
C
(x – 2) (x + 4) = 0

Explanation

To factor x² − 2x − 8, find two numbers whose product is −8 and whose sum is −2. Those numbers are −4 and 2, so the factorization is (x − 4)(x + 2) = 0, which is choice B.
