Q-3
Find the sum of the zeros of the polynomial 2x² - 8x+6
बहुपद 2x-8x+6 शून्यकों कायोगफल ज्ञात कीजिये।
Ans -​

Answer 1

$Compare \:given \: polynomial \: 2x^{2}-8x+6 \:with$

$ax^{2}+bx+c \: , we \:get$

$a = 2, b = -8 \:and \: c = 6$

$Now, \blue{ Sum \:of \:the \: zeroes}$

$= \frac{-b}{a}$

$= \frac{-(-8)}{2}$

$= \frac{8}{2}$

$= 4$

Therefore.,

$\red{ Sum \:of \:the \: zeroes} \green { = 4}$

Answer 2

Sum of zeroes = 4 .

Given :-

• 2x² - 8x + 6 = 0

To Find :-

• Sum of zeroes = ?

Solution :-

On Compare given quadratic equation with ax² + bx + c = 0 . we get,

=> a = 2 , b = -8 , c = 6

Sum of zeroes = -b/a

=> Sum of zeroes = -(-8)/2

=> Sum of zeroes = 8/2

=> Sum of zeroes = 4 .
