Vocaloid · Answer

first you'd move all the terms to one side (you can do this by subtracting 10x from both sides) to get:

9x^2 - 10x + 2

then identify your a, b, and c values, by comparing your equation to ax^2 + bx + c

finally calculate b^2 - 4*a*c

let me know if you are having trouble or want to check your solution
