Question

Find zeros of polynomial x2-7x-4

Answer 1

Let,

* a = 1
* b = - 7
* c = - 4

$\tt\:⟹ sum \: of \: the \: zeroes \: = \alpha + \beta = \frac{ - b}{a} = \frac{ - ( - 7)}{1} = 7$
$\tt\:⟹ products \: of \: the \: zeroes = \alpha \beta = \frac{c}{a} = \frac{ - 4}{1} = - 4$
Hence, it is solved.
