Question

(If one zero of the quadratic polynomial x²+x-2 is - 2.find the other zero)

Answer 1

α + β = -1

-2 + β = -1

β = 1

Answer 2

$\mathfrak {\huge {Hi !}}$

$\underline {\sf {Polynomial}}$ = $\tt {x^{2} + x - 2}$

$\underline {\sf {One\:zero}}$ =(-2)

$\tt {\alpha + \beta = \frac {-b}{a}}$

=》 $\tt {\beta = -1 + 2}$

=》 $\huge {\tt {\beta = 1}}$
