Here, watch this really long video and sponge some knowledge...

This is the quadratic formula

The discriminant tells you how many real solutions in a quadratic equation. [|what the discriminant is, and where it is in the quadratic formula]



To use this formula, first Put the numbers that represent the letters a, b and c into the equation. for example if the equation is ->

A=1 B=2 C=-3

__** Note: When there is not a number in front of x, it is equal to a 1. **__ __**If there is not a number any where else it is equal to 0**__

To Solve The Equation... step 1. Square the b value. step 2. Multiply 4 by the a value, and that sum by the c value. step 3. Add the two products together. step 4. Get the square root of the sum of the added products. step 5. Then split off into two different equations, one that is positive, one that is negative. step 6. Add or subtract the remaining numbers step 7. DIVIDE! And you are done!!!!!!!!!!!
