You can take LCM and then can add to see what's the sum.

The sum result of given expressions is given by: $\dfrac{5}{y+5}$

<h2>Given that:</h2>

To find sum of $\dfrac{3y}{y^2 + 7y + 10}$ and $\dfrac{2}{y+2}$

<h2>Finding LCM and summing:</h2>

You can take LCM and then can add to see whats the sum.

$\begin{aligned}\dfrac{3y}{y^2 + 7y + 10} + \dfrac{2}{y+2} &= \dfrac{3y}{(y+2)(y+5)} + \dfrac{2}{y+2}\\&= \dfrac{3y + 2(y+5)}{(y+2)(y+5)}\\&= \dfrac{5y+10}{(y+2)(y+5)}\\&= \dfrac{5(y+2)}{(y+2)(y+5)}\\&= \dfrac{5}{y+5}\\\end{aligned}$

Thus, the sum of given expressions is given by:

$\dfrac{5}{y+5}$

Here is a graph of the function y, both continuous and differentiable. For approximately what values of x between -5 and 5 is th

Law Incorporation [45]

From the graph you can determine the first derivative by looking at the turning points. These are where the first derivative is zero.

$y' = x(x-2)(x+2)(x-5)(x+5) \\ \\ y' = x^5 -29x^3 +100x$

Take derivative to get 2nd derivative and set equal to zero:
$y'' = 5x^4 -87x^2 +100 = 0$

Solve for x:
$x^2 = \frac{87 \pm \sqrt{87^2 -2000}}{10} \\ \\ x = \pm 1.11, \pm 4.02$
