    two quadratic functions combined by addition

    a linear function and a quadratic function combined by addition

    two linear functions combined by multiplication

    Step-by-step explanation:

    -3x² + 5

    (-4x² + 4) + (x² + 1)

    -3x² + 5

    (-3x² - x) + (x + 5)

    -3x² + 5

    (sqrt (5) - sqrt (3) x) (sqrt (5) + sqrt (3) x)
