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.

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?
