(6)m^(3)+3m^(2)-2=3m^(3)

Decide which of the following are quadratic equations : m^(3)+3m^(2)-2=3m^(3)

Decide which of the following are quadratic equations : m^(3)+3m^(2)-2=3m^(3)

If sin A+cos A=m and sin^(3)A+cos^(3)A=n then (1)m^(3)-3m+n=0 (2) n^(3)-3n+ 2m=0(3)m^(3)-3m+2n=0 (4) m3+3m+2n=0

If m is a real number such that m^(2)+1=3m the value of (2m^(5)-5m^(4)+2m^(3)-8m^(2))/(1+m^(2))

If m + (1)/(m) = sqrt3 , then find the simpliest value of (i) m^(2) + (1)/(m^(2)) and (ii) m^(3) + (1)/(m^(3)) :

m^(3)-n^(3)-m(m^(2)-n^(2))+n(m-n)^(2)
