Demonstrates how to solve for a variable under the radical that needs to isolated first after entering the given value for the other variable in a formula.


A short discussion of how compunde interest works and why the amount in a compound interest account grows more and more quickly.


Shows how to substitite the given value for the output variable, then rearranges the resulting equation in standard form. Values for a, b, and c are identified and then entered into the quadratic…


This video explains the situation we are trying to minimize or maximize and the role of the input and output variables. Then the process of finding the location and value of the requested amount is…


This demonstrates two ways of dealing with a literal equation that has parentheses which adds an extra step in the process in the first method, bu t not the second.


This shows how to decide whether you are seeking a maximum or minimum value for a quadratic function and then how to find the vertex of i ts parabola to deternine the xvalue that locates the min…


This demonstrates how to find these values for a quadratic equation of the form y = ax^2 + bx + c.


Gives the three possible answers that result from calculating a discriminant, then demonstratew with two different quadratic equations.


A quick run through the use of a^2 + b^2 = c^2 to find an unknown side of a right tirangle if we know the other two sides.


We use the slope formula to find the slope from the given points, then we use it again, inserting the discovered slope and solving for the desired missing coordintate of a third point.


Need the videos for finding tej slopes of parallel and perpendicular lines before viewing this one. This shows how to get the infromation needed for fulling in the pointslope form. You can leave…


Shows how you can create the pointslope form, then shows the entry of the given information.


Presents the use of the slope formulat we use to calculate the slopes of these special lines.




An introduction to distance, rate, and time problems where a chart is helpful to organize the information.


Demonstrating how to rearrange a formula so you don't have to this algebra every time you use it to get a specific value.
