# Complete the following table of products:

Answer :

For finding B1A2

2X x -3y

= -6xy

B1A4

2X x -5xy

= -10 y

= -10 y

B2A1

-3Y x 2x

= -6xy

B2A6

-3Y x -6x^{2}y^{2}

= 18 x (y^{(1 + 2)}) x x^{2}

= 18 y^{3} x^{2}

B3A3

4x^{2} x 4x^{2}

= 16x^{(2 + 2)}

= 16x^{4}

B3A5

4x^{2} x 7x^{2}y

= (4x7) x ( x^{2 + 2}) x y

= 28 x^{4}y

B4A1

-5xy X 2x

= (-5x2) x ( ) x y

= -10 y

= -10 y

So the final table will be
