Answer:

-5

Step-by-step explanation:

Hi, First begin by solving the quadratic equation

x^2 + 5x + 6

What two numbers multiply to get 6 but add to make 5? I would use 3 and 2

X^2 + 3x + 2x + 6

x(x+3) 2(x+3)

(x+2) (x+3)

X=-2

X=-3

These are your two solutions

-2 + -3 = -5

Answer:

$\frac{6}{k-6}$

Step-by-step explanation:

First, we can factor all of the following equations to turn that weird, huge looking thing into $\frac{(k+6)(k-6)}{(k-6)(k-10)}$ ÷ $\frac{(k-6)^2}{k(k-6)}$ × $\frac{6(k-10)}{k(k + 6)}$ . We know that division is simply multiplication by the reciprocal, so that whole equation will turn into $\frac{(k+6)(k-6)}{(k-6)(k-10)}$ × $\frac{k(k-6)}{(k-6)^2}$ × $\frac{6(k-10)}{k(k+6)}$ . Now we can cancel out some values if they are both in the numerator and denominator, which will turn that still huge looking thing into $\frac{6}{k-6}$ which is our final answer, as it cannot be simplified further.
