Question

If x=5+2√6 find value of x²+1divide by x² and x³+1divide x³

Answer 1

Step-by-step explanation:

If x=5+2√6 find value of x²+1divide by x² and x³+1divide x³

Answer 2

Answer:

$x^{2} = (5+2\sqrt{6})^{2}\\x^{2} = 25 + 24 + 20\sqrt{6} ------------ (a+b)^{2} \\x^{2} = 49 +20\sqrt{6} \\=\frac{(x+1)^{2} }{x^{2} } \\=\frac{ x^{2} +1 +2x}{x^{2} } \\=1 + 2x$
