Question

Find a quadratic polynomial whose sum of zeroes is 1/4
and product is -1​

Answer 1

Answer:

a quadratic polynomial is of the form x²- (sum of zeroes)x + (product of zeroes)

Step-by-step explanation:

so required polynomial is x²-1/4x+(-1)

x²-1/4x-1

Answer 2

$Given, \: Sum \: of \: zeroes \: = 1/4</p><p> \\ and \: product \: of \: zeros = \: -1 \\ </p><p>Then, \: the \: quadratic \: polynomial \\ = k \: [ {x}^{2} - (sum \: of \: zeroes)x + product \: of \: zeroes ] \\ k( {x}^{2} - ( \frac{1}{4} )x - 1 \\ = k( {x}^{2} - \frac{x}{4} - 1) \\ = k( \frac{4 {x}^{2} - x - 4 }{4 } ) \\ If \: k = 4, \: then \: the \: required \: quadratic \: polynomial \: is \\ 4 {x}^{2} - x - 4</p><p>$
