Find the sum, difference, or product. Simplify your answer completely. 2(2 – 5t) + t^2(t – 1) – (t^4 – 2)

To simplify the expression, we need to distribute the coefficients and combine like terms. Starting with the left side, we have: 2(2 - 5t) = 4 - 10t Moving to the right side, we have: t^2(t - 1) = t^3 - t^2 -(t^4 - 2) = -t^4 + 2 Putting it all together, we have: 4 - 10t + t^3 - t^2 - t^4 + 2 Rearranging, we have: -t^4 + t^3 - t^2 - 10t + 6 This is the simplified expression. We were not asked to find the sum, difference, or product of anything specific, so this is our final answer.
