\huge\text{Hey there!}


\mathsf{x^3 + 2x = 40}


\large\text{Subtract 40 to both sides:}


\mathsf{x^3 + 2x - 40 = 40 - 40}


\large\text{Simplify it:}


\mathsf{x^3 + 2x - 40 = 40 - 40}


\mathsf{x^3 + 2x - 40= 0}


\large\text{If you're familiar with the cubic formula use that to solve this portion:}


\large\textsf{If you're unfamiliar with the cubic formula we will study that another}\\\large\textsf{time whenever you're ready to understand it }\heartsuit


\mathsf{x = 3.22524}


\mathsf{x \approx 3}


\huge\text{Therefore, your answer should be: \boxed{\mathsf{3.22524}}}\huge\checkmark


\huge\text{Good luck on your assignment \& enjoy your day!}
