A. –8x2 – 7x + 15
B. –4x2 – x + 15
C. 4x2 + x + 15 **
D. 8x2 + 7x + 15

3 answers

2 x² + 8 - 4 x + 3 x - 6 x² + 7 = 2 x² - 6 x² - 4 x + 3 x + 8 + 7 = - 4 x² - x +15
2x2 + 8 – 4x + 3x – 6x2 + 7
A. –8x2 – 7x + 15
B. –4x2 – x + 15
C. 4x2 + x + 15 **
D. 8x2 + 7x + 15
The simplified polynomial is option B: -4x² - x + 15.
