completing the square of x12x2SolutionGiven Expression x1 2

completing the square of
x+1=2x^2

Solution

Given Expression

x+1 = 2x^2

taken all values in to one side so we get

2x^2-x-1=0 we can write this as

2x^2-2x+x-1=0

2x(x-1)+(x-1)=0(by takeing 2x as common)

(x-1)(2x+1) =0

Then

x-1 = 0, 2x+1 = 0

Therefore x = 1, x = -1/2
