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

Answer 1

x²+2x+3

Explanation:

We are to simplify the expression;

5x³+10x²+15x/5x

Factor out 5x from the numerator

= 5x(x²+2x+3)/5x

5x will cancel out both at the top and bottom to have;

x²+2x+3

Factorize

x²+2x+3

Hence the simplified form is x²+2x+3
