Question

Simplify: (4x2 + 4xy + 6y2
x) + (7y2
x + 9 xy) – (2x2+ 4xy).

Answer 1

Answer:

2x^2 + 13y^2x + 9xy

Step-by-step explanation:

$(4x { }^{2} + 4xy + 6y ^{2}x) + (7y {}^{2} x + 9xy) - (2x {}^{2} + 4xy)$

$4x {}^{2} + 4xy + 6y {}^{2} x + 7y {}^{2} x + 9xy - 2x {}^{2} - 4xy$

$2x {}^{2} + 9xy + 13y {}^{2} x$
