Factor x2 + 8.0 + 15

A. (x+8) (x+15)

B. (x+3) (x+5)

C. (x+6) (x+20)

B. (x+3) (x+5)

x^2 + 8.0 + 15 is a standard form equation (ax^2 + bx + c). When factoring standard form equations that have a coefficient of one, you want to find two numbers that add to "b" and multiply to "c". In this case, 3 + 5 equals 8.0 which is your b-value, and 3 x 5 equals 15 which is your c-value.

b

Step-by-step explanation:

to factor, just think of what 2 numbers multiplied together = 15 and added = 8. in this case, 3*5=15 and 3+5=8
