Here we're dividing a fraction (5/8) by another fraction. We could obtain the same result by inverting the divisor (2/5) and then multiplying (5/8) by (5/2).
The product is 25/16.
Thus, 2/5 divides into 5/8 25/16 times, or 1 9/16 times.
<span>P(x) = x</span>³<span> + 5x</span>²<span> – x – 5
P(x) = x</span>²(x+5) - (x + 5)
P(x) = (x + 5)(x² - 1)
P(x) = (x + 5) (x + 1)(x -1)
The answer is C. -1+-6=-7, not 7.
Given:

To find:
The simplified expression by factoring.
Solution:
Let us factor the numerator:

31x can be written as 3x + 28x.

Take 3x common in 1st two terms and 7 common in next two terms.

Make sure the remaining terms in the both brackets must be same.
Now, take out common factor (4x + 1).

In the same way, factorize the denominator:

8x can be written as 4x + 4x.

Take 4x common in 1st two terms and 1 common in next two terms.

Make sure the remaining terms in the both brackets must be same.
Now, take out common factor (4x + 1).

Substitute the terms we found for numerator and denominator:

Cancel the common factors.

The simplified expression is
