Answer:

-9[tex]x^{9} y^{5}[/tex]

Step-by-step explanation:

(-8x⁴y³)(2x⁵y²)+7x⁹y⁵  (grouping like terms)

= (-8)(2) (x⁴x⁵) (y³y²) +7[tex]x^{9} y^{5}[/tex]

= -16 [tex]x^{4+5} y^{3+2 }[/tex] + 7[tex]x^{9} y^{5}[/tex]

= -16 [tex]x^{9} y^{5}[/tex] + 7[tex]x^{9} y^{5}[/tex]

= (-16 + 7)[tex]x^{9} y^{5}[/tex]

= -9[tex]x^{9} y^{5}[/tex]
