What is the solution of the equation x2 + 4 = 0?
x = ±i
x = ±2i
x = ±2

D

Step-by-step explanation:

The question on Edge 2020:

What are the solutions to the equation x2 + 4x + 5 = 0?

A) x = −4 + 2i or x = −4 − 2i

B) x = 1 or x = 4

C) x = −2 + i or x = 2 − i

D) x = −2 + i or x = −2 − i

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
