Solve the equation by completing the square x^2-18x+58=0

We want to add something to the right side of the equation to get 81.

x^2 - 18x + 81 = 23

The final step is to factor and subtract 23. (Subtracting 23 is a unnecessary, but whatever)

(x - 9)^2 - 23 = 0

So "x" = 9 + sqrt23

step-by-step explanation:

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!
