What is the value of \(0.796 \times 0.796 - 0.204 \times 0.204\) / \(0.796 - 0.204\)?
Answer: C
The numerator is in the form \(a^2 - b^2\), which factors to \((a-b)(a+b)\).
So, the expression is \(\frac{(0.796 - 0.204)(0.796 + 0.204)}{0.796 - 0.204}\).
We can cancel out the \((0.796 - 0.204)\) term.
We are left with \(0.796 + 0.204 = 1.000 = 1\).
