= -2
Let's answer question 3 first, because by solving it through the quadratic formula, we actually get the discriminant for free and it's easy to get the axis of symmetry.
In this quadratic, 2x²- 12x + 7 the values for the quadratic formula are a = 2, b = -12, c = 7. (Read the coefficients with a for the squared term, b for the x term, c for the number).
The axis of symmetry is at x =
Remember that part? That's half of the quadratic formula.
x =
(You often see the plus or minus part, but this chat box doesn't have that key.) Also, the discriminant is the other half - the b²-4ac part. That is 12²-4(2)(7) = 144 - 56 = 88.
Thus, are the solutions, the axis of symmetry is at x =3, and the discriminant is 88.
