Question

Find the zeros in the function 3x2+ 6 = 0

Answer 1

x = ± i
`√(2)`

Explanation:

Given

3x² + 6 = 0 ( subtract 6 from both sides )

3x² = - 6 ( divide both sides by 3 )

x² = - 2 ( take the square root of both sides )

x = ±
`√(-2)`

= ±
`√(2(-1))`

= ± (
`√(2)` ×
`√(-1)`) →
`√(-1)` = i

= ± i
`√(2)`
