Answer 1

D= b square -4ac=0
a=5, b= -6, c= -2
D= (-6) square -4(5)(-2)=0
D= 76 >0
The equation has real roots
Now , using the method of completing the square,
5xsquare /5-6x/5-2/5=0
X square-6x/5=2/5
Now, multiplying-6x/5 by 1/2 and adding its square on both the side,
X square-6x/5+6/10 square = 2/5+6/10 square
(XSquare -6/10) whole square =2/5+36/100
X square-6/10)whole square = 40+36/100=76/100=root 76/10square
Now taking squareing on both
X-6/10=root 76/10
X=root 76/10+6/10
After solving this u will get the answer
