Question

16. Find the product.
fa) (x + y + 3)(x + y + 2)​

Answer 1

Answer:

We use distribution rule

$x^{2} +xy+2x+yx+y^{2}+2y+3x+3y+6$

By adding them up we get

Answer is :: $x^{2}+2xy+5x+y^{2} +5y+6$

Step-by-step explanation:

I used the rule of distribution, where each element multiply each element.

Answer 2

Step-by-step explanation:

(x+ y + 3) (x+ y +2)

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

= x²+xy+2x + xy+ y²+2y+3x+3y+ 6

= x²+2y²+ 2xy+ 5x + 5y +6
