Question

Simplify: (9 m 2 - 7 n + 4) - (8 m 2 - 3 n + 2)

Answer 1

A= m^2-4n+2

Explanation:

(9m 2 −7n+4)−(8m 2 −3n+2)

To find the opposite of 8m^2 −3n+2, find the opposite of each term.

9m^2 −7n+4−8m 2 +3n−2

Combine 9m^2 and −8m^2 to get m^2.

m^2 −7n+4+3n−2

Combine −7n and 3n to get −4n.

m^2 −4n+4−2

Subtract 2 from 4 to get 2.

m^2 −4n+2
