Art of Problem Solving: Square Root Introduction Part 2

Pupils learn to solve square root equations and rationalize denominators. Problems include those with extraneous solutions. 

There are many ways to approach finding the rational approximation of an unknown square root. Here is a problem that will help math learners make a connection between square roots and their order on a number line. As usual, determine two...

Reviewing the last problem from the previous video because he feels that he "rushed it," Sal again explains the concept of ratios as it applies to problem 6 on the practice SAT (page 472 in The Official SAT Study Guide). Additional...

Sal works through several problems involving rational and irrational numbers, and shows how to find the difference. This video is a good stepping stone for those who are preparing to take on more challenging algebra work.

Continuing his SAT review session, Sal explores problems with slopes, linear equations, and congruent angles. He begins problem 10 (geometry) but finishes the problem in the next video.
