Converting an equation to vertex form can be tedious and require an extensive degree of algebraic background knowledge, including weighty topics such as factoring. The vertex form of a quadratic equation is y = a(x - h)^2 + k, where "x" and "y" are varia
Write the expression 3x^{12}+20x^{6}+6 in quadratic form. A quadratic function is f(x) = x^2 + 6x 7. Express the function f(x) in the standard form f(x) = a(x h)^2 + k. Express the quadratic function in standard form and identify a, b, and c. k(w) = 3w +...
