a=-1 b=10 c=10
x=(-b +/- sqrt(b^2 - 4ac)) / 2a
x = (-10 +/- sqrt(10^2 - 4*(-1)*10)) / 2(-1)
x= (-10 +/- sqrt(100 + 40)) / -2
x= (-10 +/- sqrt(140)) / -2
x= (-10 +/- 2* sqrt(35)) / -2
x = 5 +/- sqrt(35)

I'm getting: x=(-b±√(b^2-4ac))/2a x =5±√35 ...I think (been a few years)...

10 + 10x - x*x = 0 a = -1
b = 10
c = 10
r = (-b +/- sqrt(b*b-4*a*c)/(2*a)
r = (-10 +/- sqrt(100+40))/(-2)
r1 = 5 - sqrt(35)
r2 = 5 + sqrt(35)
.... your mileage may vary.
BTW, what were you doing in sophmore year of high school? (No, I didn't consult any references, but I did check by back substitution. I left sophmore year of HS in 1966.)

It would be a lot easier to solve by completing the square:
Multiply both sides by -1. Move the C-term to the zero side by elimination. Take 1/2 of the the coefficient of the x-term, square it and add to both sides. Express the left side as a square. Take the square root of both sides. Isolate x on the left by moving the number to the right. The answer will have the form x = n + sqrt(m).
Or not.

1. Multiply through by -1 to get
x
2 - 10x -10
Written that way,
a = 1
b = -10
c = -10
Now does it look easier to plug into the quadratic equation?

why wouldn’t you just factor it instead.
using the AC rule
THe quadratic formula is not the solution here. It is a nice check of your work, but it rarely yields whole number answers.
Which in HS mathematics, the answers are always whole numbers
