Question

Which of the following are solutions to the equation below? Check all that apply. 15x2 - 44x + 32 = 0

Answer 1

If you want to find the solutions for this you have to factor it.  Since it's a second degree polynomial, you'll have 2 solutions.  Factoring this using the quadratic formula, you'll get factors of (5x-8)(3x-4).  Solving these for x you get x = 8/5 and x = 4/3.
