Question

7. A quadratic polynomial, whose zeroes are 1/2 ” and1/2
is
a) 4x°-4x +1 b)4x2+x-1 c) x2-4x-1 d) none​

Answer 1

Answer:

Given zeros =1/2,1/2

$let \: us \: assume \: \alpha \: and \: \beta \: are \: zeroes \: then$

Quadratic polynomial =

${x}^{2} - ( \alpha + \beta )x + \alpha \beta$

$= {x}^{2} - x + \frac{1}{4}$

$= \frac{k}{4} (4 {x}^{2} - 4x + 1)$

So your answer is a
