A. 6x +29x2 + 26x -21
B. 6x3 + 14x2 + 35x -21
C. 6x? + 29x2 - 26x +21
D. 6x +15x2 - 9x-21

Answer 1

(2x²+5x-3) × (3x+7) equals 6x³ + 29x² + 26x - 21.

Explanation:

(2x²+5x-3) × (3x+7)

6x³ + 14x² + 15x² +35x - 9x - 21

Combine like terms.

6x³ + 29x² + 26x - 21

So, (2x²+5x-3) × (3x+7) equals 6x³ + 29x² + 26x - 21.
