Answer:
Line 1: 2x^2 +2x +4
Line 2: x +6
Line 3: 12x^2 +12x +24
Line 4: 2x^3 +2x^2 +4x
Line 5: 2x^3 +14x^2 +16x +24
Step-by-step explanation:
Line 1 is the expanded form of the multiplicand. A polynomial is already in expanded form so this is simply the multiplicand.
Line 2 is the expanded form of the multiplier. It, too, is just the multiplier.
Line 3 is the sum of partial products of the least-degree term of the multiplier with each term of the multiplicand.
Line 4 is the sum of partial products of the highest-degree term of the multiplier with each term of the multiplicand.
Line 5 is the sum of lines 3 and 4.
