Today we introduced the solving quadratic equations by the quadratic formula. The formula and some examples are shown as bellows.
1. Solving radical equations 2. Solving quadratic equations by the square root property 3. Solving quadratic equations by completing the square
Radical forms also can also be represented as fractional exponents. By doing this, you can use all the rules for exponents to simplify the radical forms. Followings are the definition of fractional exponents and some examples. Product and quotient rules can be used to simplify the products and quotients of radicals. Here are some examples. In order to remove the radical in the denominators, we use the fact that we can multiply the numerator and the denominator of a fraction by the same nonzero number without changing the value of the expression. Here are some examples.
