If (x + 1)² = 55, what is the approximate positive value of x?

Solution:

Given, the expression is (x + 1)² = 55

We have to find the approximate positive value of x.

On taking square root,

x + 1 = ±√55

We know, √55 = 7.41619848

x + 1 = ± 7.41619848

x = ± 7.41619848 - 1

Approximate positive value of x = + 7.41619848 - 1

= 6.41619848

≈ 6.42

Therefore, the approximate positive value of x is 6.42

If (x + 1)² = 55, what is the approximate positive value of x?

Summary:

If (x + 1)² = 55, what is the approximate positive value of x is 6.42
