Solve the quadratic equation. (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:

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

$a+5=27i$

$a=27i-5$
