Y=x^2+12x+30
8x-y=10
sub x^2+12x+30 for y in the secodn equaiton
8x-(x^2+12x+30)=10
8x-x^2-12x-30=10
-x^2-4x-30=10
times -1
x^2+4x+30=-10
add 10 both sides
x^2+4x+40=0
use quadratic formula
we find that we have 2 imaginary roots and therefor are not on the real plane, they are not plotted on the imaginary plane
no real solution
x=-2+6i or -2-6i
the interseciton on the imaginary plane is
(-2+6i, -26+48i) or (-2-6i,-26-48i)
I’m not sure if I agree however if you put $3000 in the bank account that same bank account earns 4% interest on your total balance a year so in the real world yes that’s a good idea if you have resting money in your bank account and it earns 4% interest every year that’s incredible
