Question

How do you solve w^2-63=106

Answer 1

The solution of
`w^(2)-63=106` is 13

Solution:

Given equation is
`w^(2)-63=106`

Let us solve the given equation

When we move a number from L.H.S to R. H.S or vice – versa, there sign changes from negative to positive; division to multiplication; positive to negative; multiplication to division

`\mathrm{w}^(2)=106+63`

Add the terms in right side

`\mathrm{Now}, \mathrm{w}^(2)=169`

Taking square root on both sides, we get

`w=√(169)`

`\begin{array}{l}{w=√(13 * 13)} \\\\ {w=13}\end{array}`

Hence the value of given equation is 13

Answer 2

13

Explanation:

W^2 - 63 = 106

W^2 = 106 + 63

W^2 = 169

W = √169

W = 13
