Step-by-step explanation:
step 1. use Foil to multiply the polynomials.
step 2. (3x + 3)(2x + 6) = 6x^2 + 18x + 6x + 18 = 6x^2 + 24x + 18.
step 3. (2x + 1)(x - 2) = 2x^2 - 4x + x - 2 = 2x^2 - 3x - 2.
step 4. (x - 3)(x + 4) = x^2 + 4x - 3x - 12 = x^2 + x - 12.
'karen is making 14 different kinds of greeting cards she is making 12 of each kind how many greeting cards does she making'
ok so that is multiplication
14 times 12 since it is 12 of each and 14 of them so
14 times 12=
do you guys still do multiplication by the tower meathod or such if so, here it is
14
<span><u>12 x</u>
</span>
so it is
if you had
a b
<u>c</u><span><u> d x</u></span>
(ad)(bd)
<u>(bc)(ac) +</u>
result
first you do
2 times 4 then place it below the 2
14
<span><u>12 x</u>
</span> 8
then you do 2 times 1 then place it below
14
<span><u>12 x</u>
</span>28
then you move on the the one
1 times 4
14
<span><span><u>12 x</u>
</span>28
4
then 1 times 1<span>
</span></span> 14
<span><span> <u>12 x</u>
</span> 28
14
</span>
then we add
14
<span><span> <u>12 x</u>
</span> 28
<u>14 +</u></span>

answer is 168
Answer:
-5x³ + 3x³ + 2x + 6
Step-by-step explanation:
if that is truly the complete problem description, then the only possible answer I can think of, that makes any sense :
what do I need to add to 5x³+3x²-2x+1 to get 6x²+7 ?
the answer is
6x²+7 - (5x³+3x²-2x+1) = 6x²+7-5x³-3x²+2x-1 =
= -5x³ + 3x³ + 2x + 6
