(x^(4)-3x^(3)+2x^(2))/(x^(2)-x-30)>0

Solve the inequality (x^(2)-3x+2)(x^(3)-3x^(2))(4-x^(2))>=0

Solve : (i) (x^(2)-x)^(2)+5(x^(2)-x)+4=0 (ii) (x^(2)-3x)^(2)-16(x^(2)-3x)-36=0

If x^(2)+3x+1=0 then find x^(3)+(1)/(x^(3)),x^(4)+(1)/(x^(4)),x^(2)-(1)/(x^(2)),x^(2)+(1)/(x^(2))

((3^(x)-4^(x))*ln(x+2))/(x^(2)-3x-4)<=0

the solution set of the inequality (3^(x)-4^(x))*(ln(x+2))/(x^(2)-3x-4)<=0

(x^(2)+3x+2)^(2)-8(x^(2)+3x)-4=0

((2-x^(2))(x-3)^(3))/((x+1)(x^(2)-3x-4))>=0

The roots of x^(4) - 5x^(3) + 3x^(2) + 19x - 30 = 0 are

factorise (i) 2x^(3)-3x^(2)-17x+30 (ii) x^(3) -6x^(2)+11x-6 (iii) x^(3)+x^(2)-4x-4 (iv) 3x^(2)-x^(2)-3x+1
