Question

-x^2-3xy-y^2-8x^2-xy+6xy^2

simplify and solve please

Answer 1

`\tt \: { - x}^(2) - 3xy - {y}^(2) - {8x}^(2) - xy + {6xy}^(2)`

Collect like terms

• 
  `\boxed{ \sf \: - {x}^(2) \: and \: { - 8x}^(2) }`
• 
  `\boxed{ \sf \: - 3xy \: and \: - xy}`

`\tt \: { - 9x}^(2) - 4xy - {y}^(2) + {6xy}^(2)`

Answer 2

`-9x^2-4xy-y^2+6xy^2`
