Simplify: [tex]$\frac{x^2-4}{x^2+2 x-8} \div \frac{5 x+10}{x+4}$[/tex]

sqrt(-25)+2 sqrt(-9)= 5sqrt(-1)+2 3*sqrt(-1)= 5i+6i=11i
recall that i*i = -1 :)

The correct **expression **is,
⇒ 14i
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
**Expression **is,
⇒ √- 25 + 2√- 9
Hence, We can change it into monomial in term of i as;
⇒ √- 25 + 2√- 9
⇒ √- 5² + 2 √- 3²
⇒ 5i + 3 × 3i
⇒ 5i + 9i
⇒ 14i
Since, i² = - 1
Thus, The correct **expression **is,
⇒ 14i
