Answer 2

break it up like so\[\Large \frac{ 5x^3 }{ 5x } + \frac{ 10x^2 }{ 5x } + \frac{15x }{ 5x } \]

Answer 3

then what do you do?

Answer 4

5x^3/5x = ?
10x^2/5x = ?
15x/5x = ?

Answer 5

\(\dfrac{5x^3}{5x} + \dfrac{10x^2}{5x} + \dfrac{15x}{5x} \)

\(=\dfrac{5x\cdot x^2}{5x} + \dfrac{2\cdot 5x\cdot x}{5x} + \dfrac{3 \cdot 5x}{5x} \)

\(=\dfrac{\cancel{5x}\cdot x^2}{\cancel{5x}1} + \dfrac{2\cdot \cancel{5x}\cdot x}{\cancel{5x}1} + \dfrac{3 \cdot \cancel{5x}}{\cancel{5x}1} \)

What's left?

Answer 6

1x^2 + 3x + 4? I think im wrong :/

Answer 7

Answer 8

\(=\dfrac{\cancel{5x}\cdot \color{red}{x^2}}{\cancel{5x}1} + \dfrac{\color{red}{2}\cdot \cancel{5x}\cdot \color{red}{x}}{\cancel{5x}1} + \dfrac{\color{red}{3} \cdot \cancel{5x}}{\cancel{5x}1}\)

I colored what is left red.

Answer 9

so the answer is x^2+2x+3?

Answer 10

correct

Answer 11

can you help me with another one?

Answer 12

not now. i have to go.

Answer 13

okay :/
