Question

Simplify completely the quantity 5 times x to the third power plus 10 times x to the 2nd power plus 15 times x all over 5 times x. x^2 + 10x^2 + 15x

2^x + 6
x^2 + 2x + 3
x^4 + 2x^3 + 3x^2

Answer 1

x^2+2x+3 is your answer.

Answer 2

you would factor a 5x out of the numerator sine there is a 5x in 5x^3, 10x^2 and 15x. when you factor, it should be 5x( x^2+2x+3). The 5x on top and bottom would then cancel out, leaving x^2+2x+3 as you answer.
