Question

Yge quadrilateral polynomial whose zeros are 5 and -8 is​

Answer 1

Answer:

x^2 + 3x - 40

Step-by-step explanation:

Formula to find a quadratic polynomial when it zeroes are given -

K [ x^2 - (sum of the zeroes)x + (product of the zeroes) ]

{ Here K is a constant }

= K [ x^2 - ( 5+(-8) )x + ( 5 × -8 ) ]

Let K be 1,

= x^2 - (-3) x + (-40)

= x^2 + 3x - 40
