Question

I'm dealing with polynomials
Solve:
15x^3+10x^2
-------------------------
5x
Did I get the right answer?
5x^5

Answer 1

Solve
\[\frac{15 x^3+10 x^2}{5 x}\]
?

Answer 2

yes that is the question

Answer 3

You can simplify it but you can't solve it

Answer 4

Separate the denominator\[\frac{15 x^3+10 x^2}{5 x} \\ \\ = \frac{15 x^3}{5 x}+\frac{10 x^2}{5 x} \\ \\ =?\]

So \(15x^3\) divided by 5x gives you \(3x^2\), what about \(10x^2\) divided by 5x? What do you get?

Answer 5

5x^2?

Answer 6

2x^2 dur sorry

Answer 7

\(x^2\) divided by x is?

Answer 8

x^1?

Answer 9

Good, x^1 is x basically. So you have \(3x^2\) from \(\frac{15x^3}{5x}\) previously and 2x here, so that gives you

\[\frac{15 x^3}{5 x}+\frac{10 x^2}{5 x} \\ \\ =3x^2+2x\]

Answer 10

yes you did submit it
