Answer:
[C] 4x² − 9x + 5
Explanation:
6x² − x + 1 − (−4 + 2x² + 8x)
[ Distribute the Negative Sign ]
= 6x² − x + 1 + −1(−4 + 2x² + 8x)
= 6x² + −x + 1 + (−1)(−4) + −1(2x²) + −1(8x)
= 6x² + −x + 1 + 4 + −2x² + −8x
[ Combine Like Terms ]
= 6x²2 + −x + 1 + 4 + −2x² + −8x
= (6x² + −2x²) + (−x + −8x) + (1 + 4)
= 4x² + −9x + 5
