Ineed to know how to solve this foil problem i algebra

do: first of first bracket x first of 2nd bracket

+( first of 1st bracket x 2nd of 2nd bracket)

+(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.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
