If the square of X minus x minus 1 equals zero, find the value of x to the fifth power of x to the fourth power plus 2x plus 1 If the square of X minus x minus 1 equals zero, then the fourth power of x plus 2 x plus 1 of x

If the square of X minus x minus 1 equals zero, find the value of x to the fifth power of x to the fourth power plus 2x plus 1 If the square of X minus x minus 1 equals zero, then the fourth power of x plus 2 x plus 1 of x

X2- x -1=0, i.e. x2= x+1 denominator x^5= x2*x*x*x=(x+1)*x*x*x=(x2+x)*x*x=(2x+1)*x*x=(2x2+x)*x=(2(x+1)+x)*x=(3x+2)*x.(1)=(3x2+2x)=3(x+1)+2x =5x+3 sub-division x^4+2x+1=...

If x squared plus x minus 1 equals 0, what is the value of x squared plus 2x squared plus 2008

Because x^2+x-1=0
So x^2=1-x
So
X^3+2x^2+2008
=X (1-x)+2x^2+2008
=X^2+x+2008
=1+2008
=2009
