Khan Academy: Creating an Equation With No Solutions

Do your scholars freeze when the variable disappears when solving an equation? Support their conceptual development of these types of equations using a video lesson. Young scholars replay the video as needed or rewind to re-watch...

This equation has variables on both sides. No problem, right? Follow the steps necessary to solve this problem. Wait! Something is not right. The left side of the equation does not equal the right side of the equation. How can that be?...

How can you determine if a quadratic equation has no solutions before the problems is solved? Use the discriminant! What's the discriminant? It's part of the quadratic formula. Watch the instructor go through the necessary steps to use...

How can an equation have no solution? Well, if the original equation has a variable on each side of the equal sign, it could work out that there is no solution. Watch this video and find out just how that happens.

Two equations. What's the solution to this system? How can you solve it? Can you write the two equations in slope-intercept form? Yes, you can. Now graph each equation. Look, the lines are parallel. What does that mean? That means there...

There are many ways to solve a quadratic equation. Let's check out how to solve a quadratic equation by graphing. But first, let's find the axis of symmetry and the vertex before making a table of values. Write the values as ordered...

Shows how to complete the equation 4(x - 2) + x = 5x + __ so that it has infinitely many solutions. [1:04]

Trying to solve an equation with variables on both sides of the equation? Figure out how to get those variables together and solve the equation. Turns out, this equation has no solution. Watch this to find out why. [2:00]

You've got some algebraic fractions in an equation and their denominators are all different. Well, first you need to strategize. Then find the excluded values that make your denominator equal zero because we know the denominator cannot...

This video demonstrates how to solve a multi-step equation using the distributive property. There is one example that includes integers and demonstrates how to check your answer. [6:04]
