Answer 1

hope it is correct .. and will be helpful to you .

Answer 2

5x squ. - 6x-2=0
divide equ by 5
x squ- 6x/5=2/5........(1)


Third term= [1/2×-6/5]squ
= ( -6/10)squ
=. (-3/5)squ
= 9/25
add to equ(1)

x squ-6x/5+9/5= 2/5+9/25
(x-3/5) squ=50+45/125
( x-3/5) squ= 95/125
Taking square root both side
(x-3/5)=root95/root 125
(x-3/5)= root95/root25×5
(x-3/5) =root95/5root5
x-3/5= root 19× root 5/ 5root 5
x-3/5=root 19/5
x-3/5=+-root 19/5
x= root 19/5+3/5. or. x= - root 19/ 5+3/5
x= root19+3/5. or. x=. - Root 19+3/5



here is your Ans
.

x= 3+root19/5. or. x=3-root19/6
