Answer 2

For x² + 6² = 10² the values of x are - 8 , 8

Given :

x² + 6² = 10²

To find :

The value of x

Solution :

Step 1 of 2 :

Write down the given equation

The given equation is

x² + 6² = 10²

Step 2 of 2 :

Find the value of x

$\displaystyle \sf{ {x}^{2} + {6}^{2} = {10}^{2} }$

$\displaystyle \sf{ \implies {x}^{2} + 36 = 100 }$

$\displaystyle \sf{ \implies {x}^{2} = 100 - 36 }$

$\displaystyle \sf{ \implies {x}^{2} = 64}$

$\displaystyle \sf{ \implies x = \pm \: \sqrt{64} }$

$\displaystyle \sf{ \implies x = \pm \: 8 }$

Hence the required value of x = - 8 , 8
