expand

= 2x-6 + 15 - 10x -28x -14

simplify

= -36x -5

= 2(x - 3) + 5(3 - 2x) - 7(4x + 2)
= 2x - 6 + 15 - 10x - 28x - 14
= - 36x - 5

Answer: - 36x - 5

= 5x^6 + 4x^4 - 7x^3 - 10x^5 - 8x^3 + 14x^2 + 25x^3 + 20x -35 = 5x^6 - 10x^5 + 4x^4 + 10x^3 + 14x^2 + 20x - 35 You just multiply each term by the next one, then you organize them by how high the number is over the X of the term.

2(x - 3) + 5(3 - 2x) - 7(4x + 2)
= 2(x) - 2(3) + 5(3) - 5(2x) - 7(4x) - 7(2)
= 2x - 6 + 15 - 10x - 28x - 14
= 2x - 10x - 28x - 6 + 15 - 14
= -36x - 5

2x - 6 + 15 - 10 x - 28 x - 14
