When the coefficient of a term is 1 or -1, we don't write it, we just use the + or - sign. The coefficient of the c term is -1, because of the - sign in front of it and the lack of written coefficient. Any questions?

Y-INTERCEPT

The y-intercept is where the equation/curve/parabola cosses the y-axis.
The y-axis is where x = 0. (The x-axis is where y = 0)
To find the y-intercept:

The y-intercept must be at (0, 10)
X-INTERCEPT (ROOTS/SOLUTIONS)

We need to use the quadratic formula
The quadratic formula helps us find what values of
make the equation = 0
Quadratic formula: 

The x-intercepts are at:

6x+33-2(3x+1)
17+14
30+1
60-29
18+13
You add +7 to both sides and then divide by 9 to get the x alone.
