Answer 1

hay!!

given

⟼12m2-9m+5m-4m2-7m+10

to find

⟼Collect like terms and simplify.

answer

⟼$8m { }^{2} - 11m + 10$

solusion

Rearranging terms, we have

⟼12m2 - 4m2 + 5m - 9m - 7m + 10

⟼= (12 – 4) m² + (5 – 9 – 7) m + 10

⟼= 8m² + (– 4 – 7) m + 10

⟼= 8m² + (-11) m + 10

⟼$= 8m {}^{2} - 11m + 10$

hope it's helps you
