Question

(8m²+3m-6)-(9m-7)+(3m²-2m+4), Simplify.

Answer 1

$\textbf{Answer :}$

Now,

(8m² + 3m - 6) - (9m - 7) + (3m² - 2m + 4)

= 8m² + 3m - 6 - 9m + 7 + 3m² - 2m + 4

= (8 + 3)m² + (3 - 9 - 2)m + (- 6 + 7 + 4)

= 11m² - 8m + 5,

which is the required simplification.

Answer 2

Answer:

(8m²+3m-6)-(9m-7)+(3m²-2m+4) = 11m² -8m  + 5

Step-by-step explanation:

(8m²+3m-6)-(9m-7)+(3m²-2m+4)

first opening the bracket

sign with -ve outside bracket will change sign inside

= 8m²+3m -6 -9m + 7 + 3m²-2m+4

Putting similar terms together

= 8m² + 3m² + 3m - 9m -2m -6 + 7 + 4

= 11m² -8m  + 5
