Math 1021 section 1. 6 radical equations; equations quadratic in form; A polynomial equation is any equation of the form an xn + an-1xn-1 + +a2x2 + ax. + a0 = 0, where an (leading coefficient) , an-1 , a2, a, and a0 (constant term) are the coefficients and x is raised to power which is a non-negative integer (whole number). A linear and quadratic equation are examples of polynomial equations. When the variable in an equation occurs in a square root, cube root, and so on, it is called a radical equation. Sometimes a radical equation can be changed to a linear or quadratic equation by performing certain operations. To solve a radical equation first isolate the radical on one side of the equation, then raise each side to a power equal to the index of the radical. Be careful not to raise each term to the power, but each side.
