It is known that M is a root of the equation x's Square - 2013x + 1 = 0. Find the square of M - 2013m + m square + 1 / 2 2013m

It is known that M is a root of the equation x's Square - 2013x + 1 = 0. Find the square of M - 2013m + m square + 1 / 2 2013m

X = m is substituted into the equation to get M & # 178; - 2013m + 1 = 0, that is M & # 178; - 2013m = - 1m & # 178; + 1 = 2013m, so M & # 178; - 2013m + (M & # 178; + 1) of 2013m = - 1 + 2013m of 2013m = - 1 + 1 = 0.

2012 △ 2012 and 2012 / 2013!

Put 2012 inside
Just = 2012x [2013 / 2012 (2013 + 1)]
=2013/2014

What's 2012 times 67 / 2013
To solve the problem ideas, to simple algorithm, 3 days no one will give 100 wealth value, jump point

2012 times 67 / 2013
=（2013-1）*67/2013
=2013*67/3012-1*67/2013
=67-67/2013
=1946 out of 66

What is the value of 2013 × 2013-2013 × 2012-2012 × 2011 + 2012 × 2012

=(2013x2013-2013x2012)+(2012x2012-2012x2011)=2013x(2013-2012)+2012x(2012-2011) =2013+2012=4025
