Simplifying Radicals before Multiplying
Instances are demonstrated where simplifying radicals before multiplying are indicated.
Simplifying Rational Expressions
Simplifying rational expressions is like reducing rational numbers. First fully factor the numerator and denominator and then cancel all the common factors. The process is illustrated step by step.
Simplifying a Radical by Factoring the Radicand
Simplifying a radical by factoring the radicand is demonstrated. The goal of simplifying a radical is to make an expression easier to deal with by getting the smallest number possible under the radical sign.
Simplifying by Adding or Subtracting Common Radical Factors
A new guideline for simplifying radicals is introduced: the terms in a fully-simplified radical expression must have no common radical factors. Simplifying a radical expression by adding or subtracting common radical fac..
Simplifying the Square Root of Larger Numbers
Simplifying the square root of a larger number.
Simplifying to Find a Common Radical Factor
The process of simplifying to find a common radical factor is demonstrated.
Slope Defined
Slope is the ratio that shows the rate of change between two pints. Calculating slope using a graph is demonstrated.
Slope Formula, The
The slope formula enables you to use two ordered pairs to find slope. Sub notation is used for clarity.
Slope is the Same Everywhere on a Straight Line
The ratio of a sloped line remains the same anywhere on that line and is unaffected by positive or negative position.
Slope-intercept Form
Review of the slope-intercept form showing how to write an equation given the slope and the y-intercept, and how to write an equation to solve for the y-intercept given the slope and one point.
