Question

I need to simplify for the question

Answer 1

Answer:

$x^2 + 3xy + 4y^2$

Step-by-step explanation:

$(x - 2y)^2 + 7xy =$

$= (x - 2y)(x - 2y) + 7xy$

$= x^2 -2xy - 2xy + 4y^2 + 7xy$

$= x^2 + 3xy + 4y^2$

Answer 2

Answer:

$\tt x^2+3xy+4y^2$

Step-by-step explanation:

$\tt(x-2y)^2+7xy\\\\=x^2-4xy+4y^2+7xy\\\\=x^2+3xy+4y^2$
