3x^(2)-2x^(6)x+2=0

Which of the following equations has 2 as a root? (a) x^(2)-4x+5=0 , (b) x^(2)+3x-12=0 (c) 2x^(2)-7x+6=0 , (d) 3x^(2)-6x-2=0

If x_(1) and x_(2) are the roots of 3x^(2)-2x-6=0 then x_(1)^(2)+x_(2)^(2) is equal to

Find the greatest and least value of y= x^(3)-3x^(2) + 6x-2 on [-1,1] y is differentiable function of x and y'(x) = 3x^(2) -6x + 6= 3(x^(2) -2x+2) =3(x-1)^(2) gt 0 .

If x=2+2^(2/3)+2^(1/3) show that x^(3)-6x^(2)+6x-2=0

lim_(xrarr0) (6^(x)-3x^(2)-2^(x)+1)/(x^(2))=?
