The meaning of QUADRATIC FORMULA is a formula that gives the solutions of the general quadratic equation ax2 + bx + c = 0 and that is usually written in the form x = (-b ±√(b2 — 4ac))/(2a).
The formula for the quadratic equation is ax²+bx + c = 0, and its solution formula is x = [-b±√(b² - 4ac)]/2a. If a = 1, b = 3, c = 2, how to write this solution formula in English? A. x equals minus b plus or minus the square root of (b squared minus ...
An equation can be any two random mathematical expressions set equal to each other, such as "5x+2y-3b+sin(2)=e^x+3".A formula is a type of equation, but usually one that relates common quantities in a standard way that can be applied to solve other problems, such as the quadratic ...
