Question

Solve by factoring x^2+8x+15

Answer 1

Factor the expression:
(x + 3) (x + 5)

Answer 2

In order to factore it u have to set the first term seperate
E.J. 
(x   )(x   ), now the 2 signs are positive so the signs inside are positive as well
(x+  )(x+  ), now divide 15 in 2 numbers that can be multiplied to get 15 and added or subtracted to get 8, 5 times 3 equals 15 and when u add them you get 8 so this ones are good, so your factors would be
(x+3)(x+50

Hope this helps
