Question

X=1/2+root3, y=1/2-root3 find the value of 8xy(x^2+y^2)

Answer 1

Step-by-step explanation:

x=1/2+√3,. y=1/2-√3

On adding X & Y we get,

X+Y=4

On substructing X & Y we get,

x-y= -2√3

And on multiplying X & Y we get,

x×y=1/(4-3)

=>1

Now come onto the question,

8xy(x^2+y^2)

=>8×1(x+y)^2 -2xy

=>8(4)^2 -2×1

=>126
