Question

. Add 4y(3y2 + 5y - 7) and 2(23 - 4y2 + 5)​

Answer 1

Answer:

4y(3y2 + 5y - 7) + 2(23 - 4y2 + 5)

12y³+20y²-28y+46-8y²+10

12y³+12y²-28y +36

Answer 2

Answer:

(12y3 +20y2 - 28y) + (46 - 8y2 + 10)

=12y3 +20y2 - 8y2 - 28y +46 +10

=12y3 +12y2 - 28y +56

Step-by-step explanation:

First we'll multiply the outer term (4y and 2) to the terms present in bracket.

Then we'll put the similar terms together (like 20y2 and - 8y2, 46 and 10)

And then we'll add or subtract them according to the need (like 8y2 has to be subtracted from 20y2. and. 10 is added to 46).
