To make this easier, rewrite the equation in descending order:
\(x^{2} + 5x = 36\)
Then, move everything to one side by subtracting 36 from either side\(x^{2} +5x-36=0\)
Next, factor the equation into two binomials:
\((x+9)(x-4)=0\)
Then, split the two binomials and set them both equal to zero.
\(x+9=0;x-4=0\)
Then, simply, solve for x by isolating it:
\((x+9)-9=0-9;(x-4)+4=0+4 \\ x=-9;x=4\)
Your two answers are x=-9 and x=4
If you're interested, you can check both answers by plugging them into the equation.
Hope this helps!
