The Equation of the Tangent Line to the Curve $f ( x ) = \left( 7 x ^ { 5 } - 6 x ^ { 2 } + 3 \right) \left( x ^ { 3 } + x - 1 \right)$

The equation of the tangent line to the curve $f ( x ) = \left( 7 x ^ { 5 } - 6 x ^ { 2 } + 3 \right) \left( x ^ { 3 } + x - 1 \right)$ at the point (0, -3) is y = 3x - 3.
