Question

(ii) If p{x) = 2x2 + 4x + 6 is a quadratic polynomial then what is the value of sum of zeroes?
a) 0
b) 1
c) - 2
d) 4​

Answer 1

Step-by-step explanation:

Given that:

If p(x) = 2x² + 4x + 6 is a quadratic polynomial.

To find:what is the value of sum of zeroes?

a) 0 b) 1 c) - 2 d) 4

Solution:

Tip: If

$a {x}^{2} + bx + c = 0$

is quadratic polynomial,then sum of zeroes is given by

$sum \: of \: zeroes = \frac{ - b}{a}$

write values of a,b,c from give quadratic equation

here

a=2

b=4

c=6

$sum \: of \: zeroes = \frac{ - b}{a} = \frac{ - 4}{2} \\ \\ sum \: of \: zeroes = - 2$

Thus,

Option C is correct.
