Answer:
(n - 0.8)(n - 1) = 0.
Step-by-step explanation:
To solve the equation 25n^2 - 15n + 4 = 5n, you need to isolate the n^2 term by subtracting 5n from both sides:
25n^2 - 20n + 4 = 0
Next, you can simplify the left-hand side using the difference of squares:
(5n - 4)(5n - 1) = 0
So either 5n - 4 = 0 or 5n - 1 = 0. Solving for n, we find:
n = 0.8 or n = 1
So the simplified form of the equation is:
(n - 0.8)(n - 1) = 0.
