Equation of a Plane from Direction Vectors

Question

The lines

{l_1}

and

{l_2}

are given by

\begin{align*} &l_1: \mathbf{r} = \begin{pmatrix} - 2 \\ 1 \\ 1 \end{pmatrix} + \lambda \begin{pmatrix} 5 \\ 3 \\ - 4 \end{pmatrix}, \; \lambda \in \mathbb{R}, \\ &l_2: \mathbf{r} = \begin{pmatrix} - 2 \\ 1 \\ 1 \end{pmatrix} + \mu \begin{pmatrix} 5 \\ 4 \\ 1 \end{pmatrix}, \; \mu \in \mathbb{R}. \end{align*}

Find the equation of the plane

{p}

containing both

{l_1}

and

{l_2.}
