Complete the square for each expression. Write the resulting expression as a binomial squared

5. x^2+14x+?

6. x^2-12x+?

7. x^2-9x+?

5. 49, (x+7)²

6. 36, (x-6)²

7. 81/4, [x-(9/2)]²

Step-by-step explanation:

5. x² + 2(x)(7) + 7² = (x + 7)²

6. x² - 2(x)(6) + 6² = (x - 6)²

7. x² - 2(x)(9/2) + (9/2)² = (x - 9/2)²

the answer is a i belaeve atleast thats what my calculator just gfave me
