Simplify as much as possible:

(x sqrt(6t^3) - (tsqrt(24tx^2))
------
= x*t*sqrt(6t) - t*2xsqrt(6t)
---
= (xt*sqrt(6t)(1 - 2)
---
= -xtsqrt(6t)

For additional help with square roots, please see my own website. Click on my tutor name "rapaljer" anywhere in algebra.com. There, click on my website. From my Homepage, look for the link near the top of the page "Basic, Intermediate, and College Algebra: One Step at a Time." Then click on "Basic Algebra", then "Chapter 5", "Sections 5.01, 5.03, and 5.04." There you will find my own non-traditional explanations, examples, exercises, and answers to ALL the exercises, and solutions to many of the problems on the "MATH IN LIVING COLOR" pages that go with these explanations.

For an explanation of this topic at a slightly higher level, look in the "Basic, Intermediate, and College Algebra: One Step at a Time" topic for "Intermediate Algebra." Radicals are in "Chapter 3", sections 3.01 and 3.02 for Intermediate Algebra.

See also the FREE video from my own classes a few years before I retired! From my Homepage, look for the link "Rapalje Videos in Living Color". Then look for "Basic Algebra", and choose the "Radicals" link. You may need to download RealPlayer if you do not have it, but this is a FREE download. Like algebra.com, this is all FREE!!
