$4{a^2} + 9{b^2} – {c^2} + 12ab = 0$
${(2gg’ + 2ff’ – c – c’)^2} = 4({g^2} + {f^2} – c)(g'{^2} + f'{^2} – c’)$
A man is known to speak the truth …
${x^2} + (\sqrt 3 + 2)x + (\sqrt 3 – 1) = 0$
$x^5+8x+1$
Select correct option(s) with regards to tangent/normal drawn at any point on the curve $y=x^5+8x+1$.
(A) Tangent makes acute angle with x-axis
(B) Normal makes acute angle with x-axis
(C) Tangent makes obtuse angle with x-axis
(D) Normal makes obtuse angle with x-axis
(E) None of the options above as the angle made by tangent/normal with x-axis being acute/obtuse depends on the point chosen
