Answer 2

x²-5x-2=0

Multiply the equation throughout by 4, we get

4x²-20x-8=0

This is the same as

(2x)²-2(2x)(5)+5²-5²-8=0

(2x-5)²-25-8=0

(2x-5)²-33=0

(2x-5)²= 33

2x-5=±√33

$2x = 5± \sqrt{33} \\ x = \frac{5 ± \sqrt{33} }{2} \\ x = \frac{5 + \sqrt{33} }{2} , \: \: \: \frac{5 - \sqrt{33} }{2}$

Therefore, the roots are (5+√33)/2 and (5-√33)/2
