Answer: 2x^2-7x-15
Step-by-step explanation:
reorder the terms (x*2+3)*(x-5)
multiply the parentheses
(2x+3)*(x-5)
collect like terms (2x^2-10x+3x-15)
product= 2x^2-7x-15
Anything to the power of 0 is 1
So for the top, 2^0 = 1
For the bottom, 10^0 = 1
It is not 0, because anything that ends with 0/0 is <em>undetermined</em>, and will not result in an answer
hope this helps
