The quadratic formula is the result of completing the square for ax^2+bx+c=0 when a,b, and c are unknown values. This result is:
x=(-b±√(b^2-4ac))/(2a), we have x^2-x-2=0 so
x=(1±√(1+8))/2
x=(1±√9)/2
x=(1±3)/2
x=-1 and 2
Get rid of parenthesis, this is addition it doesn't matter how you add it will give you the same answer
3/8+2/3+1/3
3/8+3/3
3/8+1
3/8+8/8
11/8→1 3/8→1.375
The y intercept is (0,0) and the slope is 4
