Question

If a and ß are the zeroes of the polynomial f(x) = x ^ 2 - 5x + 8 , then a + ß+ aß is​

Answer 1

Answer:

a + ß + aß = 53

Step-by-step explanation:

Let A = 1 , B = 5 and C = 8

alpha = - B/A

ß = C/A

So alpha = -(-5)/1 = 5/1 = 5.

ß = 8/1 = 8.

So 5 + 8 + (5 * 8) = 13 + 40 = 53.

Therefore, a + ß + aß = 53.
