Question

If the sum of the roots of the quadratic equation ax² - 5x + 11 = 0 is 15 then the value of a is ?

Answer 1

HEY MATE YOUR ANSWER IS HERE

$given \: that \: sum \: of \: roots \: = 15$

sum of roots = 15

$sum \: of \: roots \: = - \frac{ \: coefficient \: of \: x \: }{coefficient \: of \: {x}^{2} \: }$

$= - \frac{( - 5)}{a} = 15 \\ \\ then \: a = \frac{5}{15} \\ \\ value \: of \: a = \frac{1}{3}$

THANKS FOR UR QUESTION HOPE IT HELPS
