| Find the quadratic polynomial whose<br> Sum and products of zeros are 21/8 and 5/16

tatuchka [14]

Answer:

$16x^{2} -42x+5$

Step-by-step explanation:

Sum of its zeroes= $\alpha +\beta =\frac{21}{8} \\$

Product of its zeroes= $\alpha \beta$ = $\frac{5}{16}$

Formula to form a quadratic polynomial:

$p(x)=k[x^{2} -(\alpha +\beta )x+\alpha \beta ]$

p(x)= $k[x^{2} -(\frac{21}{8} )x+\frac{5}{16}]$

p(x)= $16[x^{2} -(\frac{21}{8} )x+\frac{5}{16}]$

p(x)= $[16x^{2} -42x+5]$

The quadratic polyniomial is $16x^{2}-42x+5$
