Final answer:
To factor the sum of two cubes, we can use the formula (a³ + b³) = (a + b)(a² - ab + b²). In this case, t³ + 729 = (t + 9)(t² - 9t + 81).
Step-by-step explanation:
To factor the sum of two cubes, such as
t³ + 729
we can use the formula:
a³ + b³ = (a + b)(a² - ab + b²)
In this case, we have
t³ + 729 = (t + 9)(t² - 9t + 81)
Therefore, the factored form of
t³ + 729
is
(t + 9)(t² - 9t + 81)
