Question

Find the quadratic polynomial whose zeros are -3 and -5

Answer 1

Heya !

$x^{2} - sum of \: the \: zeroes \ + product \: of \: the \: zeroes$
=x^2 -(-3 ) +(-5)

=x^2+3-5 is the quadratic polynomial

Hope this helps you ^_^

Answer 2

Heya !!!




Sum of zeroes = ( -3 ) + (-5) = -8



And,

Product of zeroes = ( -3 ) × (-5) = 15



Therefore,


Required quadratic polynomial = X²-(Sum of zeroes)X + Product of zeroes


=> X² - (-8)X + 15


=> X² + 8X + 15
