Factor completely: x2 + 6x + 8 (x + 8)(x + 1) (x + 2)(x + 4) (x2 + 8)(x + 1) Prime

Find two numbers that multiply to 8 and add to 6 at the same time

jimthompson5910 (jim_thompson5910):

What are those two numbers?

OpenStudy (anonymous):

2 & 4

jimthompson5910 (jim_thompson5910):

So it factors to (x+2)(x+4)

jimthompson5910 (jim_thompson5910):

basically, the factorization in general is (x+first number)(x + second number)
