Answer 1

★ Hi , there !!★


here is your answer !!


given = m + n = mn = 10


ax² -5x + c




sum of zeroes = > m + n = - b / a


=> 10 = 5 / a as { m + n = 10 }



a = 1 / 2 ----------------(1)



now ,



mn = c / a => c / 1 / 2



from equation 1 ( value of a )



10 = c / 1 / 2


c => 5



hope it helps you dear !!



thanks !!

Answer 2

Heya dear ,

here is your answer,

______________

Given, polynomial = ax2 – 5x + c  ...  (1)

It is given that m and n are its zeros such that

m + n = mn = 10

From (1),

$sum \: of \: zeros \: = m + n = \frac{ - ( - 5)}{a} = \frac{5}{a} \\ \\ = > \frac{5}{a} = 10 \\ \\ = > a = \frac{1}{2}$

$and \: product \: of \: zeros = mn = \frac{c}{a} = 10 \\ \\ = > \frac{c}{\frac{1}{2} } = 10 \\ \\ = > 2c = 10 \\ \\ = > c = 5$
