" a "72," and "2," are the trook of "x^(2)-2x+4=0

If the lines L_(1) and L_(2) are tangents to 4x^(2)-4x-24y+49=0 and are normals for x^(2)-y^(2)=72, then find the slopes of L_(1) and L_(2).

If the lines L_1 and L_2 are tangents to 4x^2-4x-24 y+49=0 and are normals for x^2+y^2=72 , then find the slopes of L_1 and L_2dot

Factorise : x^(2) - x - 72
