Q:
4. Perform the indicated operation on polynomials.a. (4x2 + 5x - 7) + (2x2 - 7x - 3)b. (8m - 2n - 4) - (6m - 3n + 2)c. (30+4) (5c-2)
Accepted Solution
A:
Answer:A) 6x2-2x-10B) 2m+1n-6C) 170c-68Step-by-step explanation:4x2 + 2x2 = 6x2 5x -7x = -2x -7 + -3 = -108m - 6m = 2m -2n + 3n = 1n -4 - 2 = -634 x 5c = 170 34 x -2 = -68
