Solve the x by quadratic formula P^(2)x^(2)+(p^(2)-q^(2))x-q^(2)=0

Using quadratic formula solve the following quadratic equations: p^2x^2+(p^2-q^2)x-q^2=0,p!=0 9x^2-9(a+b)x+(2a^2+5a b+2b^2)=0

If sec alpha and cosec alpha are the roots of the equation x^(2)-px+q=0 , then a) p^(2)=p+2q b) q^(2)=p+2q c) p^(2)=q(q+2) d) q^(2)=p(p+2)

lim_(x rarr0)(sqrt(4^(2)+p^(2))-p)/(sqrt(x^(2)-q^(2)-q))

If the roots of the equation (1-q+(p^(2))/(2))x^(2)+p(1+q)x+q(q-1)+(p^(2))/(2)=0 are equal then show that p^(2)=4q

If the lines p(p^(2)+1)x-y+q=0 and (p^(2)+1)^(2)x+(p^(2)+1)y+2q=0 are perpendicular to the same line, then the value of p is

The lines p(p^(2)+1)x-y+q=0 and (p^(2)+1)^(2)x+(p^(2)+1)y+2q=0 are perpendicular to a common line for

The lines p(p^(2)+1)x-y+q=0 and (p^(2)+1)^(2)x+(p^(2)+1)y+2q=0 are perpendicular to a common line for
