What is the formula for solving quadratic equations?

All quadratic equations come in the form ax2 + bx + c = 0 where a is the coefficient of x2 and b is the coefficient of x. An exmple of a quadratic would be,
2x2 + 4x -6 = 0
In the above case, the coefficient of x2 is 2, so A = 2 and likewise the coefficient of x is 4, so B = 4 and C = -6.
The formula for solving quadratic equations is, formula for solving quadratic equations
We then subsitute our values for a, b and c into the above equation, and we get, formula with subituted values for a, b and c into it Which when simplified becomes, simplified version of formula
and of course, the sqyare root of 64 is 8. We then calculate the first value of X. This comes from the plus sign in the equation, we get, plus not minus
So one possible value of X is, 1
We then calculate the second possible value of x, to do this we use the minus sign in our equation, minus part of the equation
Therefore, for the quadratic equation 2x2 + 4x -6 = 0 the possible values for x are 1 or -3.
