Answer:
[tex]3x^2+3y^2+6xy-5x-5y+2[/tex]
Step-by-step explanation:
[tex]3(x+y)^2 -5(x+y) + 2[/tex]
[tex]\mathrm{Expand}\:-5\left(x+y\right)+2[/tex]
[tex]-5x-5y+2[/tex]
[tex]\mathrm{Simplify}\:3\left(x+y\right)^2[/tex]
[tex]3\left(x^2+2xy+y^2\right)[/tex]
[tex]3x^2+3\times \:2xy+3y^2[/tex]
[tex]3x^2+6xy+3y^2[/tex]
[tex]=3x^2+3y^2+6xy-5x-5y+2[/tex]
Answer:
3x^2 + 6xy + 3y^2 -5x -5y + 2
Step-by-step explanation:
3(x+y)^2 -5(x+y) + 2
3(x^2 + 2xy + y^2) -5x -5y + 2
Mulyiply the parantheses by 3,
3x^2 + 6xy + 3y^2 -5x -5y + 2
