Factoring Trinomials: a = 1

Question 5 • Common Core Algebra I B-IC

Which expression is the factored form of x2 – 7x + 10?

Answer
A
(x + 3)(x + 4)
B
(x – 3)(x – 4)
C
(x – 2)(x – 5)
D
(x + 2)(x + 5)

Explanation

To factor x² − 7x + 10, find two numbers that multiply to 10 and add to −7. Those numbers are −2 and −5, so x² − 7x + 10 = (x − 2)(x − 5). The correct choice is (x − 2)(x − 5).
