Question

Multiply: (2m³ + 3n) (5m - 1)​

Answer 1

we can use FOIL method(first,outer,inner,last)

(2m3 + 3n) (5m - 1)

2m3×5m + 2m3×(-1) + 3n×5m + 3n×(-1)

10m4 - 2m3 + 15mn - 3n

= 10m4 + 13m2n -3n

don't be angry if my answer is wrong

hope it helps

Answer 2

Answer:

By multiplying 2m3 by 5m we get= 10m4 And By multiplying 2m3 by 1 we get=2m3

Now multiplying 3n by 5m we get=15mn and by multiplying 3n by 1 we get=3n..

so by combining the above answers the final answer is =10m4 - 2m3 + 15mn - 3n....
