If using the method of completing the square to solve the quadratic equation x^2 -4x +10 =0, which number would have to be added to complete the square?

4 would have to be added to complete the square.

Step-by-step explanation:

We are given the following quadratic equation the question:

We have to form a whole square to solve the quadratic equation.

We add and subtract the square of the coefficient of x.

Thus, we added and subtracted 4 in the quadratic equation to make it a complete square.

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
