Use the discriminant formula to find the number of x-intercepts in the graph of the equation. x2 – 3x + 2 =y

b2 - 4ac

  2

Step-by-step explanation:

The values of a, b, c are ...

  a = 1, b = -3, c = 2

Then the discriminant is ...

  d = b^2 -4ac

  d = (-3)^2 -4(1)(2) = 9 -8 = 1

The discriminant is positive, so there are two x-intercepts.

Additional comment

The indications given by the discriminant are ...

  d > 0, 2 real roots (2 x-intercepts)

  d = 0, 1 real root (1 x-intercept)

  d < 0, 2 complex roots (0 x-intercepts)

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
