Photosynthesis uses 660-nm light to convert CO2 and H2O into glucose and O2. Calculate the frequency of this light.

3.1 SOLVING QUADRATIC EQUATIONS: * A QUADRATIC is a polynomial whose highest exponent is 2. * The "standard form" of a quadratic equation is: ax + bx + c = 0 with "a", "b" and "c" representing real numbers, and "a" is not equal to zero. * What do we mean by a root of a quadratic A solution to the quadratic equation. * How many roots does a quadratic have Always two. In order to solve such equations, we will need to employ one of the following methods: 1. Factoring (Equation must be written in standard form) 2. The Quadratic Formula (Equation must be written in standard form) 3. Square root principle 4. Completing the Square 1) Factoring: is the easiest method if you can fac
