Answer:
(x+5)(x+3)
Step-by-step explanation:
x^2+8+15
Factoring is just like (x+_)(x+_)
1st step is multiply the 1st and the last term
x^2 x 15= 15x^2
Think 2 numbers that
a) when you multiply is equal to 15
b) when you add is equal to 8
The two numbers are 3 and 5
Rewrite the expression as x^2+3x+5x+15
Group the expression in two terms
(x^2+3x)+(5x+15)
Identify the common factor of the first binomial
x is the common factor of the first binomial
Write the binomial like this x(x+3)
The common factor of the second binomial is 5
5(x+3)
The expression now is x(x+3)+5(x+3)
Add the outside factors then copy the inside factors(if equal)
(x+5)(x+3)
Therefore, the factored form is (x+5)(x+3)
