Answer:
How do you find the sum of factors of a quadratic equation?
Let r and s be the factors for the quadratic equation such that x^2+Bx+C=(x−r)(x−s) where sum of factors (r+s)=−B and the product of factors rs = C r = -2 - u s = -2 + u Two numbers r and s sum up to -4 exactly when the average of the two numbers is \frac{1}{2}*-4 = -2.
How do you solve a quadratic equation?

<u>Answer:</u>
26%
<u>Step-by-step explanation:</u>
We are given that the percentage of people accessing the Internet increased from 61 % in 2000 to 87% in 2012.
So we can describe the change as an absolute change in terms of percentage points by calculating the difference in the two percentages:
Absolute change in terms of percentage = 87 - 61 = 26%
Therefore, there is a 26% absolute change in the percentage of people accessing the internet.
