Question

Another day, another math problem

Answer 1

4x+2h+5

Explanation:

`((2(x+h)^(2)+5(x+h)) - (2x^(2) +5x) )/(h) \\`

For now I'm just going to ignore the denominator for simplicity

`(2(x^(2)+2xh+h^(2))+5x+5h) - (2x^(2) +5x)\\(2x^(2)+4xh+2h^(2)+5x+5h) - (2x^(2) +5x)\\(4xh+2h^(2)+5h)\\\\((4xh+2h^(2)+5h))/(h)\\ 4x+2h+5`

Final step just distributes the division
