Answer: using the discriminant to find the number of solutions to a quadratic equation b^2-4ac. positive discriminant indicates that the quadratic has <u>two distinct real number solutions.</u> The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

<span>2+3(x-3)+1-5(2-x)
The first thing we must do is distribute...
2 + 3x - 9 + 1 - 10 + 5x
Then we must combine like terms. We can combine terms with an x together and we can combine terms without an x together.
2 - 9 + 1 - 10 = -16
3x + 5x = 8x
So our simplified expression is C. 8x - 16</span>
