An equation and the first step in its solution are shown below. Equation: x2 + 6x - 9 = 0
Step 1:
x2 + 6x + h = 9+ h
What value of h is used to solve the equation by the method of completing the square?
O A. 9
B. 18
O C. 6
D. 36

A

Step-by-step explanation:

To get the third term in completing the square, take half the middle term and square it. Half of 6 is 3, and 3^2 is 9.

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!
