Step-by-step explanation:
-7 / ( x^2 -2x -15)
Factor the denominator
-7
----
(x-5) ( x+3)
The excluded values are when the denominator is equal to zero

Factor 3 from both terms:
3 (x² - 7)
To me, that's as far as you should need to go. But if you want to get
completely carried away, you could go one step further, since you have
the difference of two squares:
3 (x + √7) (x - √7)
Of course, there's no end now, because the last binomial could be
considered another difference of two squares, so you'd have to
factor that too:
3 (x + √7) (√x + ⁴√7) (√x - ⁴√7)
but to me, this would be nonsense.

Now you have 6 5/10 - 1 9/10, but since first numerator is less than the second numerator you need to borrow from the whole number. 6 5/10 = 5 10/10 + 5/10 = 5 15/10. Now just subtract the whole numbers and the numerators.
5 15/10 - 1 9/10 = 4 6/10 simplify to 4 3/5.
The value of the solution after subtraction is,
⇒ 4 3/5
We have to give that,
An expression to solve,
⇒ 6 1/2 - 1 9/10
Now, change the fraction into an improper fraction,
⇒ 6 1/2 - 1 9/10
⇒ 13/2 - 19/10
⇒ 65/10 - 19/10
⇒ (65 - 19) / 10
⇒ 46/10
⇒ 23/5
⇒ 4 3/5
Hence, the Solution of the fraction is. 4 3/5

remember revers distributive
ab+ac=a(b+c)
so
2b=2(b)
8=2(4)
2b+8=2(b)+2(4)=2(b+4)
the factored form is 2(b+4)
