which one of the following sets has elements as odd positive integers (a) S={x in R|x^(3)-8x^(2)+19x-12=0} b) S={x in R|x^(3)-9x^(2)+23x-15=0} c) S={x in R|x^(3)-7x^(2)+14x-8=0} d) S={x in R|x^(3)-12x^(2)+44x-48=0}

Solve the quadratic equation 8x^(2)-14x+3=0 (i) When xepsilonI (integers) (ii) When xepsilonQ (rational numbers)

I. 2x^(2) + 17x + 35 = 0" "II.8y^(2) - 14y-15 = 0

If x^(2)-8x+15=0 and (x-2)(x-p)=0 and one root is common then p is

If the roots of (x^(3)-Kx^(2)+14x-8)=0 are in G.P then K=

B= [x//x^(2)-x-12=0} C={x//x^(2) -8x + 15 =0, then B uuC=
