-2x+10^5 this should be I guess
That’s the answer and also the steps to getting that answer
Multiply each term in the first set of parentheses by each term in the second set, then combine like terms.
7x x 3x^2 = 21x^3
7x x -4x = -28x^2
7x x 5 + 35x
-6 x 3x^2 = -18x ^2
-6 x -4x = 24x
-6 x 5 = -30
Combine like terms to get:
21x^3 - 46x^2 + 59x - 30
-4.878-(-8.96) can be changed to -4.878 + 8.96 because when you subtract a negative it becomes a positive so the answer would be 4.082 or B
