Question

If -1 is a real zero of the polynomial p(x) =x²-7×-8,then the other zero is​

Answer 1

Answer:

We Konow that Sum of roots =

$\alpha + \beta$

=

$- b \div a$

=-(-7)/1

$\alpha + \beta = 7$

Given one of the root is -1

$- 1 + \beta = 7 \\ \beta = 8$

8 is the other Zero of the polynomial
