pls solve this with steps​

Answer 1

Answer:

is this your maths homework

Answer 2

Answer:

$(1) \tt \implies(2x-1)(x+2)$

$\tt \implies2x^{2}+4x-x-2$

$\tt \implies2x^{2}+3x-2$

$\tt(6) \implies x(\frac{{x}^{2}}{2}+xy+{y}^{2})+xy(\frac{{x}^{2}}{2}+xy+{y}^{2})$

$\tt \implies\frac{{x}^{3}}{2}+{x}^{2}y+x{y}^{2}+\frac{{x}^{3}y}{2}+{x}^{2}{y}^{2}+x{y}^{3}$
