Question

Find the product

(i) (3x + 1) ( 5y +x)

(ii) ( x + 2y) ( 2x -y)​

Answer 1

I) 3x^2+15xy+5y+x

II) 2x^2+3xy-2y^2

Answer 2

Step-by-step explanation:

3x multiply 5 y + 3x multiply x

plus 1 multiply 5y plus 1 multiply x

x

=15xy plus 3x² plus 5y plus x.

=15xy+3x²+5y+x

b) x multiply 2x - x multiply y

plus 2y multiply 2x - 2y

multiply y

=2x²-xy+4xy-2y²

=2x²+3xy-2y²
