(a+bi)(a+bi)=7-24i a^2+2abi-b^2=7-24i now identify real and imaginary parts: a^2-b^2=7 2ab=-24 and solve this system for a and b
apparently im only supposed to get values of -4 and 4 for a...i get something different

Other answers:

because first i isolate for b = -12/a then i get 7 = (a-(12/a))(a+(12/a))
a=-12/b substitute in 1ยบ equation: 144/b^2-b^2=7 144/b^2=7+b^2 144=7b^2+b^4 new variable: b^2=x 144=7x+x^2 or x^2+7x-144=0 solve this
x = -16, 9
b^2 = -16 b^2 = 9 cant take b^2 = -16
so b = +/- 3
right
so: b^2=9 b=+-3
ok, i got it now...plug +/- 3 in equation
thanks!
in a=-12/b
