please solve these questions correctly,
tomorrow is my exam ​

Answer 1

Answer:

Step-by-step explanation:

1. (x+y)(2x+3y)-(x+y)(x+1)

= x(2x+3y) + y(2x+3y) - { x(x+1) + y(x+1) }

= 2$x^{2}$ + 3xy + 2xy + 3$y^{2}$ - { $x^{2}$ + x + xy + y }

= 2$x^{2}$ + 3xy + 2xy + 3$y^{2}$ - $x^{2}$ - x - xy -y

= 2$x^{2}$ - $x^{2}$ -x + 3xy + 2xy - xy + 3$y^{2}$ - y

= $x^{2}$ -x + 4xy + 3$y^{2}$ -y

This is the ans.

I can't write 2nd question because it is too time consuming thing so....

I'll suggest you to solve all question by yourself..

& don't forget to make me as brianliest...!!!  :) :) :)
