Description:

This course provides a working knowledge of college-level algebra and its applications. This is equivalent to a three credit college algebra course at most colleges.

Emphasis is on solving linear and quadratic equations, word problems, and polynomial, rational and radical equations and applications. Students perform operations on real numbers and polynomials, and simplify algebraic, rational, and radical expressions. Arithmetic and geometric sequences are examined, and linear equations and inequalities are discussed. Students learn to graph linear, quadratic, absolute value, and piecewise-defined functions, and solve and graph exponential and logarithmic equations.

Other topics include solving applications using linear systems, and evaluating and finding partial sums of a series.

StraighterLine courses are accepted at any college that awards credit for courses approved by the American Council of Education and at StraighterLine's regionally accredited partner colleges. Courses come with up to 10 hours of one-on-one, on-demand, online tutoring.
