Math week 12 Blog Post -Edited

This week in math week 12, we re-learned how to substitute y=mx+b but with a quadratic, to solve the quadratic version, you must have 2 quadratic equations. The first step in this is to make sure Y or X is isolated generally i like to isolate Y,  and make sure they have no coefficients, and that you have an x2 to make sure you have a quadratic equation. Now that you have that you have one of the variables isolated, you use that solution and put it into the other solution wherever you see the variable you isolated on the other solution. Next you want to subtract one end to another making one side equal to 0 (Generally you subtract the soltion without x2)          

Now you want to find the 0’s, because this will allow you to find the y axis. Finding the 0’s will help you complete the equation. Once you find the 2 zero’s, you replace it in any of the equations finding the y axis but it has to be the same equation.
