Question

Find the product of the zeroes of the polynomial y^2 + y-42.

please guys give me answer fast ​

Answer 1

$let \: the \: two \: zeroes \: be \: \alpha \: and \: \beta$

$we \: know \: that \: \\ sum \: of \: zeroes \: = - b \div a$

$\alpha + \beta = - 1 \div 1$

So sum of zeroes of the polynomial = -1
