If you put a second-degree equation into the form
ax2 + bx + c = 0,
then
x = (-b ± (b2 - 4ac)½) ÷ 2a.
Remember to follow the proper order of operations (parentheses first, etc.). Note that the ± will result in two answers, as should be expected from a second-degree equation. If you are doing a word problem, substitute each answer into the problem to see if one is or both are ridiculous (I call it the ridiculous test; it saved me several times). Also remember that raising something to the power of ½ is the same as calculating its square root. I hope this is what you're looking for. Good luck.

How do you know if a quadratic equation will have one two or no solutions How do you find a quadratic equation if you are only given the solution Is it possible to have different quadratic equation?
Draw the graph of the equation. the solution is/are the points where the line cuts the x(horisontal) axis .
What is the solution of a quadratic equation called?
Sum
What do you find when you determine the discriminant?
Whether or not that there is a solution to a quadratic equation,
What is x2-3x equals 2?
This is a quadratic (2nd order polynomial) equation. The solution to x can be found as follows: subtract 2 from both sides: x2 -3x - 2 = 0. The solution can be found by the quadratic formula:(3 +- sqrt(17))/2 ---> 3.56155 and -0.56155
What is the formula of a quadratic equation?
The quadratic equation in standard form is: ax2 + bx + c = 0. The solution is x = [-b ± √b2- 4ac)] ÷ 2a You can use either plus or minus - a quadratic equation may have two solutions.
