    4x^3 + 8x^2 – 25x – 50
    Steps
    (4x^3 + 8x^2) + (-25x – 30)
    Factor out 4x^2 from 4x^3 + 8x^2: 4x^2(x + 2)
    Factor out -25 from -25x – 50: -25(x + 2)
    = 4x^2(x + 2) – 25(x + 2)
    Then, factor out common term (x + 2)
    = (x + 2)(4x^2 – 25)
    Factor 4x^2 – 25: (2x + 5)(2x – 5)
    = (x + 2)(2x + 5)(2x – 5)
    Which the answer to this is the 3rd option.
