Question

simplify: (2y^3+3y-7) - (8y-6) + (4y^3-2y+1)​

Answer 1

Answer:

= 6y³ + 9y -12

Step-by-step explanation:

= (2y³ + 3y - 7) - (8y - 6) - (4y³ - 2y + 1)

= (2y³ + 4y³) + (3y + 8y -2y) -7 - 6 + 1

= 6y³ + 9y -12

Answer 2

Answer:

$6y^{3}-7y$

Step-by-step explanation:

(2y^3+3y-7) - (8y-6) + (4y^3-2y+1)​

$2y^{3}+3y-7-8y+6+4y^{3}-2y+1\\= 2y^{3}+4y^{3}+3y-8y-2y-7+6+1\\= 6y^{3}+3y-10y-7+7\\= 6y^{3}-7y+0\\= 6y^{3}-7y$

$6y^{3}-7y$ is your answer
