So I am doing my algebra home work and I get stuck on these three problems.
x^219x+72 from there idk what to do because nothing multiplies up to 72 and adds up to 19.
Same for this one.
x^225x+48
And
x^2+990
(X+15) (x6)

algebra 2 
Kuai,
x^2 19x + 72
Prime
x^2 25x +48
prime
Or you can use quadratic formula
ok
(x 6)(x+15)
