Answer 2

Answer:

Given:

• 1) 17m - 12n - 1 + 4 - 13m - 12n.
• 2) 4m + 3 + 4m - 24n + 3 + 30m - 5 + 30m - 24n-5.

Find:

• What is the sum of the polynomials?

Calculations:

1) 17m - 12n - 1 + 4 - 13m - 12n.

→ 30m - 24n - 3

2) 4m + 3 + 4m - 24n + 3 + 30m - 5 + 30m - 24n-5.

→ 68m - 48n - 4

Adding (1) with (2) we get:

→ 30m - 24n - 3 (+) 68m - 48n - 4

→ 30m + -24n + -3 + 68m + -48n + -4

→ (30m + 68m) + (-24n + -48n) + (-3 + -4)

→ 98m + -72n + -7
