Use factoring by grouping to solve the following equation.
4x^3 + 8x^2 − 9x − 18 = 0
x = 1 (smallest value)
x = 2
x = 3 (largest value)

  • math - ,

    4x^2(x+2)-9(x+2)=0
    (x+2)(4x^2-9)=0
    I assume you can take it from here. The second term is a difference of two squares, so it can be further factored.
