100 POINTS AND BRAINIEST! Given that f(x) = 0.25x^2 - 0.125x - 12.25 has a root at x = -6.75, use the axis of symmetry to find the other root of the function.

Step-by-step explanation:

x = 54/97 = 0.557

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "6.75" was replaced by "(675/100)". 3 more similar replacement(s)

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

          (125/1000)*x-(1225/100)*x-(-(675/100))=0

Final result :

 2x2 - x - 98
