Explain this to me and show me the answer

Hello from MrBillDoesMath!

( x^2 - 10x + 23 ) /23

Discussion:

if f(x) = x^2 - 2, then  find (  f(x-5) - f(5) ) /  x

f(x-5) = (x-5)^2 - 2 = x^2 -10x + 25 - 2 = x^2-10x+23

f(5) = 5^2 -2 = 25 -2 = 23

The ratio of these values is   ( x^2 - 10x + 23 ) /23

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
