Can you please help me to solve this equation 2x6 x5 8x24x0
Can you please help me to solve this equation.
2x^6 -x^5 +8x^2-4x=0 (r1= 1/2, r2= 1+j)
Solution
zeroes are x=1/2 ,x=1+i,x=1-i
that is (2x-1)(x-1-i)(x-1+i)=2x3-x2+6x-2
2x6-x5+8x2-4x=0
x(2x5-x4+8x-4)=0
x(x4(2x-1)+4(2x-1))=0
x(2x-1)(x4+4)=0
x=0, (2x-1)(x4+4)/(2x3-x2+6x-2)=0
x=0,x2+2x+2=0
x=0,x=-1+i, -1-i
so the zeroes are
x=0,1/2,1+i,1-i,-1+i,-1-i
