Explanation :
To find the remainder when the polynomial y³ + y² - 2y + 5 is divided by y - 5, we can use the Remainder Theorem.
The Remainder Theorem states that when a polynomial f(x) is divided by x - a, the remainder is equal to f(a).
In this case, we want to find the remainder when y³ + y² - 2y + 5 is divided by y - 5.
We can substitute y = 5 into the polynomial to find the remainder.
f(5) = (5)³ + (5)² - 2(5) + 5
= 125 + 25 - 10 + 5
= 145
Therefore, the remainder when y³ + y² - 2y + 5 is divided by y - 5 is 145.
