To simplify the given expression, we first need to factor it.
3x^2 + 6xy + 3y^2= 3(x^2 + 2xy + y^2)= 3(x + y)^2
Next, we factor the second expression:
4x^2 - 4y^2= 4(x^2 - y^2)= 4(x + y)(x - y)
Therefore, the simplified expression is:3(x + y)^2 + 4(x + y)(x - y)
To simplify the given expression, we first need to factor it.
3x^2 + 6xy + 3y^2
= 3(x^2 + 2xy + y^2)
= 3(x + y)^2
Next, we factor the second expression:
4x^2 - 4y^2
= 4(x^2 - y^2)
= 4(x + y)(x - y)
Therefore, the simplified expression is:
3(x + y)^2 + 4(x + y)(x - y)
