Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

To Add:-

4y(3y²+5y-7),2(y³-4y²+5) and -8(-y + 2)

Solution:-

[4y(3y²+5y-7)]+[2(y³-4y²+5)] + [-8(-y + 2)]

(12y³+20y²-28y)+(2y³-8y²+10)+(8y-16)

12y³+2y³+20y²-8y²-28y+8y+10-16

=14y³+12y²-20y-6

Therefore the proof for the answer is verified
