xP = (9 + x2)(x + 3)

Reorder the terms:
xP = (9 + x2)(3 + x)

Multiply (9 + x2) * (3 + x)
xP = (9(3 + x) + x2(3 + x))
xP = ((3 * 9 + x * 9) + x2(3 + x))
xP = ((27 + 9x) + x2(3 + x))
xP = (27 + 9x + (3 * x2 + x * x2))
xP = (27 + 9x + (3x2 + x3))
xP = (27 + 9x + 3x2 + x3)

Solving
xP = 27 + 9x + 3x2 + x3
