Here to find the value of m we have to use formula Tanθ= |2√(h2 – ab)/(a + b)| Now compare given equation with ax2 + 2hxy + by2 = 0,      We get, a = 5m - 4, b= -6y and h = -m/2 Now use .....

Here, we make quadratic equation taking x as variable. x = {b ∓ √[b2 - 4ac]}/2a or, x  =  {(y - 5) ∓ √[( y - 5)2  +  4.2(y2 - y - 2)]}/2.2 or, 4x =  {(y - 5)  ∓ √[( y - 5)2 .....

ere we have given equation is, x^2-y^2-2x+6y-8=0 To find seperate equation we need to factorise it. So,   x^2-y^2-2x+6y-8=0 or, x2-2x-y2+6y-8=0 or,  2x2-2x-(y2-6y-8)=0 Comparing this with ax2+bx+c=0 , we get, a=2, b=-2 .....
