a, b, c, A and C are real numbers that satisfy the equation (ax^2+bx+c)^2=Ax^4+16x^3+28x^2+24x+C How many possible ordered triples of (a,b,c) are there?

Given circle Γ and a point P outside of Γ, 2 lines l1 and l2 are drawn such that both pass through P. l1 intersects Γ at A and B, and l2 intersects Γ at C and D, with C between D and P. If PA=44,PB=294 and PC=56, what is PD?

Lim x4-9/x2+4√3-15 X~√3

Yes your answer is right and you need to multiply 4.18 to get the final correct answer
