Answer:
y = 2x(x - 21)
Step-by-step explanation:
The given quadratic function y = -40x + 2x^2 - 2x
This can be rearranged as
y = 2x^2 - 2x - 40x
Here the Greatest Common Factor is 2x, we can take it out and write the remaining term in parenthesis.
y = 2x(x - 1 -20)
y = 2x(x - 21)
That's the answer.
Hope this will helpful.
