(5x^2 - 3x)(8x^2 + 4x)

timurjin [86]

For this case we have the following expression:

$(5x ^ 2-3x) (8x ^ 2 + 4x)$

To find the product, we apply distributive property that states:

$(a + b) (c + d) = ac + ad + bc + bd$

So:

$(5x ^ 2) (8x ^ 2) + (5x ^ 2) (4x) - (3x) (8x ^ 2) - (3x) (4x) =\\40x ^ 4 + 20x ^ 3-24x ^ 3-12x ^ 2 =\\40x ^ 4-4x ^ 3-12x ^ 2$

ANswer:

$40x ^ 4-4x ^ 3-12x ^ 2$

There are 11 women and 9 men in a certain club. If the club is to select a committee of 2 women and 2 men, how many different su

Sunny_sXe [5.5K]

We can tell it’s not a permutation because it’s picking two people. Order doesn’t matter.

The number of total possible groups of men is 9 C 2 = 9!/((9-2)!(2!)) = 36

The number of total possible groups of women is 11 C 2 = 11!/((11-2)!(2!)) = 55

55 * 36 = 1980 different groups in the committee
