Question

Complete the square for each expression. Write the resulting expression as a binomial squared. x^2-10x+_____

Answer 1

`(x-5)^(2)`

Explanation:

`ax^(2) + bx + c`

Take the value for b, divide it by 2 and square it to get the value for c.

In this case, b = -10.

- 10 ÷ 2 = -5

-5^2 = 25

So x^2 - 10x +25 is your quadratic equation which is equal to

`(x-5)^(2)`
