1. The missing value that makes the polynomial x^2-6x+? A perfect square quadratic is...___

2. What makes this equation a perfect square? X^2+18x+__

1. The missing value is 9

2. The missing value is 81

Step-by-step explanation:

1. To find the missing value of a perfect square you divide the center term (-6 as is -6x) by two to get 3 then square the three to get 9

To check this write it as the simplified form (x-3)^2 and multiply it out again using foil.   x times x is x^2,  -3 times x is -3x ( this happens twice adding up to the -6x), and -3 times -3 is 9 making it x^2 -6x +9

2. Follow the steps for the previous problem to get the same answer for this one. Divide 18 (middle term) by 2 making 9. Then square the 9 making 81.
