"Write the polynomial as the product of two binomials"


x(5x+12)+5(5x+12)


I tried to solve this problem by distributing, and got:
(5x squared + 12x)+(25x+60), then I used F.O.I.L. to solve the binomial and got: 125x cubed + 300x squared + 300x squared + 720x, then I reduced it to:
125x cubed + 600x squared + 720x

When i looked at the anwser it is not the same as mine. Can someone please tell me how to solve this problem.
 
x(5x+12)+5(5x+12)
Foil:
5x2+12x +25x+60
Simplify:
5x2+37x+60
Factor:
(x+5)(5x+12)
