Question

subtraction:
2(y3 -6y2 +9) from 6y(-2y2+y - 3)​

Answer 1

Answer:

$- 14 {y}^{3} + 18 {y}^{2} - 18y - 18$

Step-by-step explanation:

$6y( - 2 {y}^{2} + y - 3) - 2( {y}^{3} - 6 {y}^{2} + 9)$

$= - 12 {y}^{3} + 6 {y}^{2} - 18y - 2 {y}^{3} + 12 {y}^{2} - 18$

$= - 14 {y}^{3} + 18 {y}^{2} - 18y - 18$
