Completing the square
alrighty
minus 31 both sides
x²+12x=-31
take 1/2 of the linear coefient and square it
12 is the linear coefient
12/2=6, (6)²=36
add that to both sides
x²+12x+36=36-31
factor perfect square trinomial
(x+6)²=5
square root both sides, remember to take positive and negative root

x+6=+/-√5


so what you want to write is
x+6=√5 and
x+6=-√5

the solutions
minus 6 both sides

x=-6+√5 and -6-√5

Find the slope of the line that passes through (10,4) and (7,9)
Mkey [24]

I will take you the steps to obtain the slopes passing two points

step 1 : list the parameters

\begin{gathered} \text{from (10, 4)} \\ x_1=10,y_1=\text{ 4} \\ \text{from (7,9)} \\ x_2_{}=7,y_2=\text{ 9} \end{gathered}

step 2: Apply the equation to obtain the slope between two points

\begin{gathered} \text{slope = }\frac{rise}{fall}=\frac{y_2-y_1}{x_2-x_1} \\  \\ \Rightarrow\frac{9\text{ - 4}}{7\text{ - 10}}\text{ =}\frac{5}{-3} \\  \\ slope=-\frac{5}{3} \end{gathered}
