somebody plz help with these math problems (FOIL method)?

1) d^2+5d+6

lol im not doing anymore

I'm not going to go through here and do each one

but just remember that FOIL means

multiply the first of each of the 2 quantities

multiply the 2 values on the outside

multiply the 2 on the inside

multiply the last of the quantities

example 12:

F = 2x * 5x = 10x^2

O = 2x * 2y = 4xy

I = 3y * 5x = 15xy (combine the 4xy and 15xy)

L = 3y * 2y = 6y^2

10x^2 + 19xy + 6y^2

d^2+3d+2d+6 = d^2+5d+6

above is the answer to number 1. You might be able to see how to do it better if you ignore the numbers for a minute and make each a letter. (A+B)(C+D) then just multiply as follows

A times C

A times D

B times C

B times D

put the correct sign in between the answers and youve got it.

1.) (d+2)(d+3)

F: first

O: outer

I: inner

L: last

Multiply the first variables in each group: d * d = d^2

Multiply the outer variables: d * 3 = 3d

Multiply the inner variables: 2 * d = 2d

Multiply the last variables of each group: 2 * 3 = 6

d^2 + 2d + 3d + 6

= d^2 + 5d + 6

Do the same thing for all of them.

theres not really that much work to show,

1. d^2+5d+6

2.z^2+3z-28

3.m^2-13m+40

4.2x^2+7x-30

5.14a^43-a+20

6.8x^2 -10xy-3y^2

7.7v^2+31v+12

8.21s^2-38s+16

9.8g^2-14gh-15h^2

10.8a^2+2a-3

11.14y^2-23y+3

12.10x^2+19xy+6y^2

90% sure they are right but you might wanna check the answers. theres no real work invovled either you know it or you dont
