Find the product and write in simplest form.

Problem 1:

(2t + 1)(10t² - 2t - 4)

Solution:

2t(10t²) - 2t(2t) - 2t(4) + 1(10t²) - 1(2t) - 1(4)

20t³ - 4t² - 8t + 10t² - 2t - 4

20t³ - 4t² + 10t² - 8t - 2t - 4

20t³ - 6t² - 10t - 4

Problem 2:

(3n-4)(n²+5n-4)​

3n(n²) + 3n(5n) - 3n(4) - 4n² - 4(5n) + 4(4)

3n³ + 15n² - 12n - 4n² - 20n + 16

3n³ + 15n² - 4n² - 12n - 20n + 16

3n³ + 11n² - 32n + 16
