+(2nd of 1st bracket x 1st of 2nd bracket)
+ (2nd of 1st bracket x 2nd of 2nd bracket)
== 10n -16n +20n+32= 14n+32
Hey there!
When multiplying binomials, keep in mind that you have to be very careful when you multiply.
(-2n-4)(-5n-8)
You can split it up so it is easier to distribute.
-2n(-5n-8)
10n+16n
-4(-5n-8)
20n+32
Now, add like terms.
10n+16n+20n= 46n
46n+32 is the answer.
I hope this helps, DM me with any questions you might have.
