Simplify

Question

7x^2+45x+18/(x^3+12x^2+36x)

Please help.

Thank you.

Answer 1

7x^2+45x+18 = (7x+3)(x+6)
x^3+12x^2+36x = x(x+6)^2

so, dividing, you are left with

(7x+3)/(x(x+6))

Answer 2

(7x+3)/x(x+6)^2 can be simplified to

(7x+3)/(x^2+6x)^2 which can be simplified to...

(7x+3)/(x^4)+(6x^2)
