Introduction
Introduction:
- Students will learn to simplify and perform operations on radical expressions and equations
- Students will be able to find the sum, difference, product and quotient of radical expressions
- Students will be able to solve radical equations
- Students will be able to identify the conjugate of the radical expressions and use it to solve radical equations
Task
