Quadratic equation
help me pls​

Answer 1

Answer:

1)
`image`

2)
`image`

3)
`image`

4)
`image`

5)
`image`

6)
`image` (Because square root from -16 doesn’t exist in real numbers, so it’s to be imaginary.)

7)
`image`

8)
`image`
So, the solutions are:

`x = (1)/(2) + (3√(2))/(2)`

`x = (1)/(2) - (3√(2))/(2)`

9)
`x = (3 √(5) + 2)/(3)`

10)
`image`
