Question

Two values of x that are roots of xsquared+2x-6=0

Answer 1

The two values of x are

1.65 , -3.65

Answer 2

Two values of x that are :

`x=-√(7)-1`

`x=√(7)-1`

Explanation:

Given=
`x^2+2x-6=0`

To find = Two values of x

Solution :

`x^2+2x-6=0`

Adding and subtracting 1 in the equation :

`x^2+2x+1-1-6=0`

`(x^2+2* x* 1+1^2)-1-6=0`

`(x+1)^2-7=0`

`(x+1)^2=7`

`(x+1)=\pm √(7)`

Two values of x that are :

`x=-√(7)-1`

`x=√(7)-1`
