The number of positive integral solutions of,(x^(2)(3x-4)^(3)(x-2)^(4))/((x-5)^(2)*(2x-7)^(6))<=0 is 1 (b) 2 (c) 3 (d) 4

The biquadratic equation, two of whose roots are 1+i , 1-sqrt(2) is A) x^(4)-4x^(3)+5x^(2)-2x-2=0 B) x^(4)-4x^(3)-5x^(2)+2x+2=0 C) x^(4)+4x^(3)-5x^(2)+2x-2=0 D) x^(4)+4x^(3)+5x^(2)-2x+2=0

Find the roots of the quadratic equations by applying the quadratic formula.(i) 2x^(2)-7x+3=0 (ii) 2x^(2)+x-4=0 (iii) 4x^(2)+4sqrt(3)x+3=0( iv )2x^(2)+x+4=0

4 (2x-3) ^ (2) - (2x-3) -14 = 0

2 ^ (2x) + 2 ^ (x + 2) -4.2 ^ (3) = 0

If x^(4)-4x^(3)+2x^(2)-4x+1=0 then x is

If x in R - {0} then minimum possible value of the expression (1)/(7)[(3x^(2)+(4)/(3x^(2))+1)^(2)-2(3x^(2)+(4)/(3x^(2)))+4]
