Question

Find x
(X+1)squared=20

Answer 1

x = ±2
`√(5)` - 1

Explanation:

`(x+1)^2=20`

Take the square root of both sides to cancel the square:

x + 1 = ±
`√(20)`

Simplify the radical:

x + 1 = ±2
`√(5)`

Subtract 1 from both sides:

x = ±2
`√(5)` - 1

Answer 2

Explanation:

x(x+1)=√20

x²+x=4.472

x²+x- 4.472=0
