The product of 2x and x -3y is 

The product of -2x²y² and -7x³y³ 

a³ × 4 a²¹ × 5a²⁵ =

Add 2a (b - c + a), 2b (b - c - a) and 2c (a + b - c) 

If ab, bc and ac are the length, breadth and height respectively of a cuboid then its volume is 

Multiply (x - 4) and (2x + 7) 

97² = 

If a + b + c = 9 and ab + bc + ca = 26, then the value of a³ + b³ +c³ - 3abc is

Add 5a³, -3a³, -1/2a³

Which of the following is a polynomial expression?
