Question

someone help please last quetion been at it for5 hours fan and medal
A quadratic equation is shown below:

3x2 − 16x + 2 = 0

Part A: Describe the solution(s) to the equation by just determining the radicand. Show your work. (5 points)

Part B: Solve 9x2 + 3x − 2 = 0 by using an appropriate method. Show the steps of your work, and explain why you chose the method used. (5 points)

Answer 4

For part b, factorization will work.
9x^2 + 3x - 2 = 0
9x^2 + 6x - 3x - 2 = 0
3x(3x + 2) - 1(3x+2) = 0
(3x-1)(3x+2) = 0
x = 1/3, -2/3

Answer 5

For A use this:

Quadratic equation: \(ax^2+bx+c=0\)

Discriminant of quadratic formula: \(b^2-4ac\)
a = 3, b = -16, c = 2

Answer 6

If \(b^2-4ac\) is
positive → 2 real solutions
0 → 1 real solution
negative → 0 real solutions
