a+b=-7
rearrange:
b= -a-7=-(a+7)
substitute into:
ab=30
-a(a+7)=30
-a^2-7a-30=0
a^2+7a+30=0
x = complex number, therefore there are no two Real numbers that exist that satisfy these two conditions.
The two numbers are:-(1/2) i (root(71) - 7i)
and:
(1/2) i root(71) + 7i)
Approximate values: a = -3.5 - 4.21307 i, b = -3.5 + 4.21307 i
