    Answer:

    x⁵ + 5x³ + 7x² + 35

    Step-by-step explanation:

    (x² + 5) (x³ + 7)

    To distribute binomials (expressions with two terms), you can use the FOIL method (First, Outer, Inner, Last):

    x⁵ + 7x² + 5x³ + 35

    To put into standard form, rearrange from highest power to lowest power:

    x⁵ + 5x³ + 7x² + 35
