You will need to find the equations of the perpendicular bisector of the two sides and then find the intersection of those two lines. Choose two sides and use midpoint formula to find their midpoints.

Solve the quadratic equation.<br> (a + 5)2 +36 = 9

Andrej [43]

Answer:

No solution unless you want to solve for an imaginary number which in that case $a=27i-5$

Step-by-step explanation:

$(a+5)^{2} +36=9$

$(a+5)^2=-27$

$a+5=\sqrt{-27}$

Here you can stop and say "no solution" since you cannot square root a negative number, but if you want you can still solve for an imaginary number:

$a+5=\sqrt{-1} \sqrt{27}$

$a+5=27i$

$a=27i-5$
