Answer 1

Question:–

☆ Find the products of the following.

a. (2x + 3y + 4) × (2x + 3)

Answer:–

☆ (2x + 3y + 4) × (2x + 3)

= 2x(2x + 3y + 4) + 3y(2x + 3y + 4) + 4(2x + 3y + 4)

= 4x² + 6xy + 8x + 6xy + 9y² + 12y + 8x + 12y + 16

= 4x² + 9y² + 8x + 8x + 12y + 12y + 6xy + 6xy + 16

= 4x² + 9y² + 16x + 24y + 12xy + 16
