Question

What are the roots of the equation? x² + 3x - 18 = 0

Answer 1

`x` = -6

`x` = 3

Step-by-step explain

`x^(2)` = 3
`x` - 18 =0

`x^(2)` =6
`x` - 3
`x` - 18 = 0

`x` x (
`x` + 6) -3
`x` - 18 = 0

`x` x (
`x` + 6) - 3(
`x` = 6)=0

(
`x` = 6) x (
`x` 3) = 0

`x` +6 = 0

`x` - 3 = 0

`x` = -6

`x` = 3
