Kyle is using the general form of a quadratic equation to derive the quadratic formula. he reaches the step in his proof that states x2 + b a x = - c a . which term must he add to complete the square?

Step-by-step explanation:

There are some fractions there that are not visible.

Here it is with the fractions in place.

To complete the square, take half of the x-term coefficient, and square it.

The x-term coefficient is .

Take half of it, or .

Now square it: .

That is what you must add to complete the square.

the answer to the expression is 83
