The Quadratic Formula: Satisfying Conditions

Now you have a quadratic equation with all terms to one side and a solution of zero. You must identify your coefficients (a, b, and c) for use in the quadratic formula.http://www.youtube.com/watch?v=EG9_-1strY4  

In the equation x^2 - 3x + 5 = 0, a is, in fact, the number 1. Coefficient b is -3 and c is 5.http://www.youtube.com/watch?v=EG9_-1strY4  

Once you have identified the coefficients, you may use them in the quadratic formula to find out the value(s) of x.http://www.purplemath.com/modules/quadform.htm

The Pythagorean Theorem Quiz

If you answered E. 5, then you're correct. If you didn't, you can try to go back now and solve for the correct answer. Otherwise, read on for a detailed explanation of how to arrive at the right answer.

First, you must remember the pythagorean theorem is a squared plus b squared is equal to c squared. Now you can plug in the numbers you've been given. That leaves you with  three squared plus four squared equals c squared. Three squared is nine, and four squared is 16. Add those together to get 25. You're not done because 25 is equal to c squared. Take the square root of both sides to find that c equals five.

Learn Geometry: How to Find the Area of a Square

After you have learned how to find the area of a square, you can use it for everyday applications. If you are making a garden, you may want to put stakes in all four corners to "see" the sides, and measure them to find how much soil or fertilizer you will need for the area. If you want to find the area of a wall for paint or wall paper, find the area of the wall and follow the instructions on the paint can for coverage recommendations.
