Finding Roots of an Equation

Resources

In mathematics, the roots of a function are the x-values that make y = 0. For example, the roots of the polynomial $y=x^{2}-4$ are 2 and -2, since Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle 0 = x^2 - 4 /implies 0 = (x - 2)(x + 2) /implies x = -2, 2} .
