Solve the quadratic equation.

x^2 = -4

don't know where to start, would appreciate if someone would be able to explain the answer in detail!

x = ± 2i

Step-by-step explanation:

The equation has no real roots, gut has complex roots

Given

x² = - 4 ( take the square root of both sides )

x = ±

  = ±

[ Note that = i ]

  = ± × = ± 2i

answer: y=4000x+14000

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
