They also use zero and negative exponents to simplify expressions. Students use concepts of the powers of 10, scientific notation, and significant digits with related computation. Students use more sophisticated techniques to factor polynomials including common binomial factors and grouping. Students solve equations with radicals and recognize extraneous roots. They also apply this content in solving problems which involve the Pythagorean Theorem.
Students utilize various transformations in solving inequalities.
They recognize the difference between conjunction and disjunctin with respect to inequalities involving absolute value. Finally, they graph systems of inequalities. Students are exposed to various types of functions. Mastery of them will come in a later algebra course. Statistics is used to introduce graphing on the line and probability is used to help review fractions.
