If AM and GM of x and y are in the ratio p: q, then x: y is : a) p - sqrt(p^(2)+ q^(2)) : p +sqrt (p^(2)+ q^(2)) b) p +sqrt(p^(2) - q^ (2) ) : p- sqrt(p^(2)-q^(2)) c) p : q d) p + sqrt(p^(2) + q^(2)) : p-sqrt(p^(2) + q^(2))

Let the polynomials be (1) -13q^(5) + 4q^(2) + 12q (2) (x^(2) + 4 ) ( x^(2) + 9) (3) 4q^(8) - q^(6) + q^(2) (4) - ( 5)/( 7) y^(12) + y^(3) + y^(5) Then ascending order of their degree is

Subtract : 4p^(2) + 5q^(2) - 6r^(2) + 7 from 3p^(2) - 4q^(2) - 5r^(2) - 6

If the difference of the roots of the equation,x^(2)+px+q=0 be unity,then (p^(2)+4q^(2)) equal to: (1-2q)^(2)(b)(1-2q)^(2)4(p-q)^(2)(d)2(p-q)^(2)

If the difference of the roots of the equation,x^(2)+px+q=0 be unity,then (p^(2)+4q^(2)) equals to: (1+1q)^(2) b.(1-2q)^(2) c.4(p-q)^(2) d.2(p-q)^(2)

If the difference of the roots of x^(2)-px+q=0 is unity,then p^(2)+4q=1b .p^(2)-4q=1c*p^(2)+4q^(2)=(1+2q)^(2)d4p^(2)+q^(2)=(1+2p)^(2)

Divide the given polynomial by the given monomial.( i (5x^(2)-6x)-:3x (ii) (3y^(8)-4y^(6)+5y^(4))-:y^(4)( iii) 8(x^(3)y^(2)z^(2)+x^(2)y^(3)z^(2)+x^(2)y^(2)z^(3))-:4x^(2)y^(2)z^(2)(iv)(x^(3)+2x^(2)+3x)-:2x(v)(p^(3)q^(6)-p^(6)q^(3))-:p^(3)q^(3)

In Q.No.7,HCF(a,b) is pq(b)p^(3)q^(3)(c)p^(3)q^(2) (d) p^(2)q^(2)
