Factor (difference of squares) the binomial 25x^2-4 and find one of its factors

Lunna [17]

Step-by-step explanation:

Hey, there!

Here,

Given that:

$= 25 {x}^{2} - 4$

we need to find factor,

As it is in a^2-b^2 form as per its factor (a+b) (a-b), keeping same formula here,

25x^2 means (5x)^2

and 4 means 2^2

Now, it would be,

$= ( {5x)}^{2} - {2}^{2}$

$= (5x + 2)(5x - 2)$

Therefore, it's factor would be (5x+2)(5x-2).

Hope it helps....

A group of students planned to chip in to raise a total of $100 for one of their friends’ birthday party but 5 persons couldn’t

lilavasa [31]

Answer:

Step-by-step explanation:

Let the number of students be x, then

Initial amount per student was:

100/x

After it becomes:

100/(x - 5)

Since amount increased after, it can be shown as:

100/x + 1 = 100/(x - 5)

Multiply each term by x(x - 5) to get rid of the fraction:

100(x-5) + x(x - 5) = 100x
100x - 500 + x² - 5x - 100x = 0
x² - 5x - 500 = 0

Positive solution of this quadratic equation is

x = 25

Amount each person paid after:

$100 / (25 - 5) = $5
