Learning to solve quadratics is a mainstay of the algebra curriculum and usually requires a great deal of trial and error. Many of the advanced scientific calculators made by Casio, such as the fxES and the fxMS, feature the ability to solve quadratics. If not, rewrite the equation as necessary.
Let's look at an example of an algebra word problem. Algebra Word Problems Linda was selling tickets for the school play. She sold 10 more adult tickets than children tickets and she sold twice as many senior tickets as children tickets.
Let x represent the number of children's tickets sold. Write an expression to represent the number of adult tickets sold.
Write an expression to represent the number of senior tickets sold. Write an equation to represent the total ticket sales. How many children's tickets were sold for the play? How many adult tickets were sold? How many senior tickets were sold? As you can see, this problem is massive! There are 5 questions to answer with many expressions to write.
Solution A few notes about this problem 1. In this problem, the variable was defined for you. If this had not been done for you, you might have written it like this: For the first expression, I knew that 10 more adult tickets were sold. An equation is written with an equal sign and an expression is without an equal sign.
For the second expression, I knew that my key words, twice as many meant two times as many. So my expression was 2x. We know that to find the total price we have to multiply the price of each ticket by the number of tickets.
Word problems are the most difficult type of problem to solve in math. So, where can you find quality word problems WITH a detailed solution? The Algebra Class E-course provides a lot of practice with solving word problems for every unit!

For the WINDOW, you can put in the min and max values for \(t\), and also the min and max values for \(x\) and \(y\) if you want to. In this tutorial, we will be looking at solving a specific type of equation called the quadratic equation. The methods of solving these types of equations that we will take a look at are solving by factoring, by using the square root method, by completing the square, and by using the quadratic equation.
