Question

If α and β are the zeroes of a quadratic polynomial x²+ 5 x - 5 , then :

Answer 1

Step-by-step explanation:

Then,

$\alpha + \beta = \frac{ - coefficient \: of \: x}{coefficient \: of \: {x}^{2} } = - 5$

and,

$\alpha \beta = \frac{constant \: term}{coefficient \: of \: {x}^{2} } = - 5$
