Solve the equation in the complex number system X^2+x+8=0

Find the Solution for

1x2+1x+8=0

using the Quadratic Formula where

a = 1, b = 1, and c = 8

x=−b±b2−4ac−−−−−−−√2a

x=−1±12−4(1)(8)−−−−−−−−−−√2(1)

x=−1±1−32−−−−−√2

x=−1±−31−−−−√2

The discriminant b2−4ac<0

so, there are two complex roots.

Simplify the Radical:

x=−1±31−−√i2

x=−12±31−−√i2

Simplify fractions and/or signs:

x=−12±31−−√i2

which becomes

x=−0.5+2.78388i

x=−0.5−2.78388i

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

da freeck kinda math is this just drop out
