Answer 1

Answer:

$Q1.add$

$1.(x {}^{2} - y {}^{3} ) + 2x {}^{2} + 3y {}^{3}$

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

$2.(x {}^{4} - 2y {}^{2} ) + 2x {}^{4} - 7y {}^{2}$

$= 4x {}^{4} - 9y {}^{2}$

$Q2)simplify$

$1.2x {}^{2} + 3y {}^{2} - 8x {}^{2} + 7y {}^{2}$

$= - 6x {}^{2} + 10y {}^{2}$

$2.12xy - 5x {}^{3} - 24xy + 18xy$

$= 6xy - 5x {}^{3}$
