Collect like terms

  • [tex] \boxed{ \sf \: - {x}^{2} \: and \: { - 8x}^{2} }[/tex]
  • [tex] \boxed{ \sf \: - 3xy \: and \: - xy}[/tex]

[tex] \tt \: { - 9x}^{2} - 4xy - {y}^{2} + {6xy}^{2} [/tex]

Answer:

[tex]-9x^2-4xy-y^2+6xy^2[/tex]

Step-by-step explanation:

[tex]-x^2-3xy-y^2-8x^2-xy+6xy^2[/tex]

group like terms:

[tex]\implies -x^2-8x^2-3xy-xy-y^2+6xy^2[/tex]

combine like terms:

[tex]\implies -9x^2-4xy-y^2+6xy^2[/tex]
