Write a quadratic function with zeros -1 and 5.

Shalnov [3]

Answer:

$x^2+4x-5$

Step-by-step explanation:

Zeros of a quadratic equation are -1 and 5.

Sum of zeros = -1 + 5 = 4

Product of zeros = (-1)(5) = -5

The quadratic equation will be :

$x^2+(\text{sum of zeros})x+\text{product of zeros}\\\\=x^2+4x-5$

So, the required quadratic equation is $x^2+4x-5$ .
