using by the method of completing Square
​

Answer 1

value of x will be 3/4 by completing the square method

Answer 2

Answer:

L.t.= M.t.×M.t./4× F.t.

X×X/ 4×4x²

X²/16x²

1/16

4x²+x+1/16-1/16-3

(2x)²+2(2x)(1)+(1)²-1/16-4

(2x+1)²-1×(-64)/16

(2x+1)²-64/16

(2x+1)²-4

(2x+1)²=(4)²

2x+1=2

2x=2-1

2x=1

X=1/2 or x=-1/2
