Hey there !
Solution :
Equation = x² - 2 √ 2 x - 30 = 0
Let us solve this sum using Completing the square method.
=> x² - 2√2 x = 30
Now we must divide 2 in the term 2√2 x
We get, √ 2 as the answer. Now we must add this number √ 2 on both sides of the equation.
=> x² - 2√2 x + √ 2 = 30 + √ 2
=> ( x - √ 2 )² = 30 + √ 2
Taking square root we get,
=> x - √ 2 = ± √ ( 30 + √ 2 )
=> x = √ 2 ± √ ( 30 + √ 2 )
Hope my answer helped :-)
