Question

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.

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.

Answer 1

nightowlPart A)The discriminant of 3x2 − 16x + 2 is 232. That tells us there are 2 real solutionsPart B) solve by factoring9x2 + 3x − 2 = 0(3x+2)(3x-1)=03x+2 = 0 or 3x-1 = 0
x = -2/3 , 1/3
