Which of the following expressions is equivalent to (5x^(2)-6x+7)-(3x^(3)+4x^(2)-8) ? Choose 1 answer: (A) -3x^(3)+x^(2)-6x-1 (B) -3x^(3)+x^(2)-6x+15 (C) -2x^(3)-6x+15 (D) -2x^(3)-6x-1

Subtract and Change Signs: Subtract the second polynomial from the first one by changing the signs of the second polynomial and combining like terms. (5x^(2)-6x+7) - (3x^(3)+4x^(2)-8) = 5x^(2)-6x+7 - 3x^(3) - 4x^(2) + 8Combine Like Terms: Combine like terms. -3x^(3) + (5x^(2) - 4x^(2)) - 6x + (7 + 8) -3x^(3) + x^(2) - 6x + 15Check Answer Choices: Check the answer choices to see which one matches our result. The correct answer is (B) -3x^(3) + x^(2) - 6x + 15.

Q. Which of the following expressions is equivalent to

\left(5 x^{2}-6 x+7\right)-\left(3 x^{3}+4 x^{2}-8\right)

\newline

Choose

1

answer:

\newline

(A)

-3 x^{3}+x^{2}-6 x-1

\newline

(B)

-3 x^{3}+x^{2}-6 x+15

\newline

(C)

-2 x^{3}-6 x+15

\newline

(D)

-2 x^{3}-6 x-1

Subtract and Change Signs: Subtract the second polynomial from the first one by changing the signs of the second polynomial and combining like terms. $\newline$ $(5x^{2}-6x+7) - (3x^{3}+4x^{2}-8) = 5x^{2}-6x+7 - 3x^{3} - 4x^{2} + 8$
Combine Like Terms: Combine like terms. $\newline$ $-3x^{3} + (5x^{2} - 4x^{2}) - 6x + (7 + 8)$ $\newline$ $-3x^{3} + x^{2} - 6x + 15$
Check Answer Choices: Check the answer choices to see which one matches our result. $\newline$ The correct answer is (B) $-3x^{3} + x^{2} - 6x + 15$ .
