Answer:
[tex]\huge\boxed{\sd -9, \ 1}[/tex]
Step-by-step explanation:
Given quadratic equation is:
x² + 8x - 9 = 0
Using mid-term break formula
x² + 9x - x - 9 = 0 (When we multiply middle terms, we get side terms as answer which is mid term break formula.)
Taking common
x(x + 9) - 1(x + 9) = 0
Take (x + 9) common
(x + 9)(x - 1) = 0
According to zero's method:
Either:
x + 9 = 0 OR x - 1 = 0
x = -9 OR x = 1
