5y^(2)+10y

(i) x^(2) + 6x + 5 = 0 (ii) y^(2) -10y+21 = 0

The foci of the ellipse 9x^(2)+ 5(y^(2)-10y +25)=45 are

The acute angle between the line represented by x^(2)-6xy+5y^(2)+10x-4y+9=0 is

Show that the equation x^(2)-6xy+5y^(2)+10x-14y+9=0 represents a pair of lines. Find the acute angle between them. Also find the point of intersection of the lines.

Using division show that 3y^(2)+5 is factor of 6y^(5)+15y^(4)+16y^(3)+4y^(2)+10y-35

If p(y)=y^(3)-5y^(2)+5y+10 , then find p(2) +p(-2).

If p(y)=y^(3)-5y^(2)+5y+10 , then find p(2) +p(-2).
