Multiply the following using the vertical multiplication method:
3x2 - 5x+1
xx2 +2x+4
—————-
A. 3x4 + x
+10x7 - 18x + 4
B. 3x4 – x2 + 3x2 + 18x+4
O
C. 3x4 + x2 +3x? - 18x+ 4
O
D. 3x4 + x2 +10x2 + x + 4

C) 3 + + 3 - 18x + 4

Step-by-step explanation:

Using vertical multiplication method, we will multiply each number separately with another.

      3 - 5x + 1

 (×)   + 2x + 4      

    3 - 5 +       [ Multiplying with  3 - 5x + 1 each of them separately]

             6 - 10 +   2x

                    + 12 - 20x + 4

After adding and subtracting all the values, we get,

    3 + + 3 - 18x + 4

Therefore, option C is the answer. In this way, we can do vertical multiplication method.
