Plug 'a', 'b', and 'c' from the equation into the formula. When you do that, the formula becomes a pair of numbers ... one number when you pick the 'plus' sign, and another number when you pick the 'minus' sign. Those two numbers are the 'solutions' to the quadratic equation you started with.
The Quadratic formula in mathematics is used to solve quadratic equations in algebra. The simplest way to solve these equations is to set each of the factors to zero and then solve each factor separately.
Put the equation into the following form: ax2+bx+c=0 Then plug the values for a, b, and c into the quadratic formula. Do the arithmetic to find the value for x twice, once using + after the -b in the numerator, and once using - after -b in the numerator. You will get two different values for x, one using + and the other using -. Give both possible values for x when you give your answer. Here is the quadratic formula: x= -b+-square root(b2-4ac)/2a
A quadratic equation is univariate: it has only one variable. A quadratic equation cannot have two variables. So, if b and c are known then it is a quadratic equation in a; if a and b are known it is a quadratic in c.Another Answer:-The question given is Pythagoras' theorem formula for a right angle triangle
