What constant do you need to add to each quadratic to complete the square? 1. x^2 - 4x = 0 16 2. x^2 - 8x = 6 4 3. 3x^2 + 18x = 24 9

1. 4

2. 16

3. 9

Step-by-step explanation:

Completing the square requires a quadratic in form. Once in this form, calculate .

1.

2.

3. Requires you divide everything by 3 first.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
