Question

Write a quadratic equations whose zeroes is 5 and -8

Answer 1

Answer:

x² - 5x - 8 + o

Step-by-step explanation:

α + β = -b/a

αβ = c/a

The general form of a quadratic equation is ax² + bx + c

Since α+β = 5,

-b/a = -(-5)/1

Since αβ = -8,

c/a = -8/1

Therefore, a = 1. b = -5, c = -8
