Normally a domestic freezer is best set to â18 Â°C (0 Â°F) or colder, as that's what the expiration dates for many food items are based on. It's also a requirement for freezers in restaurants, supermarkets & other places that sell food (at least here in Europe) to maintain a temperature of at most -18 Â°C.
Note: When you're dealing with quadratic equations, it can be really helpful to identify a, b, and c. These values are used to find the axis of symmetry, the discriminant, and even the roots using the quadratic formula. It's no question that it's important to know how to identify these values in a quadratic equation.
1 For example, 6x 2 + 2x + 1 = 0 is a quadratic equation while 6x + 2 is not a quadratic equation. 2  Factoring-The process of breaking apart of an equation into factors (or separate terms) such that when the separate terms are multiplied together, they produce the original equation.3  For example, x 2 - x - 2 = (x+1)(x-2).efinitions. 1  Quadratic Equation-An equation that can be written in the form ax2 + bx + c = 0. 2  For example, 6x 2 + 2x + 1 = 0 is a quadratic equation while 6x + 2 is not a quadratic equation.
