Question

if x+1/2x=2 find the value of x^2+1/4x^2

Answer 1

Step-by-step explanation:

x + 1 /2x = 2

x + 1 = 4x

x = 4x - 1

Now put that in the equation

(4x - 1)^2 + 1 / 4* ( 4x -1) ^ 2

16x^2 + 1 - 8x + 1 / 4 * ( 16x^2 + 1 - 8x)

16x^2 - 8x + 2 / 64x ^2 - 32x + 4

8x^2 - 4x + 1 / 16x^2 - 8x + 1
