# Évariste Galois

Remember the quadratic formula from high school? This is the formula used to find the roots of a polynomial with degree 2 such as ${\displaystyle x^{2}+2x+1}$. Similar formulas exist to find the roots of polynomials of degree 3 and 4. But there is no analogous formula for degree 5 polynomials. Though this knowledge has a long and complex history, the result is largely understood due to efforts of one tragic man Évariste Galois.
