Q:
# Factor the trinomial below. x2 – 3x – 40 A. (x + 5)(x + 8) B. (x + 5)(x – 8) C. (x – 5)(x – 8) D. (x – 5)(x + 8)

Accepted Solution

A:

Two numbers that can multiply to equal 40 but subtract to equal - 3.

[tex]40 = 8 \times 5 \\ - 8 + 5 = - 3 \\ \\ (x - 8)(x + 5)[/tex]

[tex]40 = 8 \times 5 \\ - 8 + 5 = - 3 \\ \\ (x - 8)(x + 5)[/tex]
