f p(x) = 2x2 + 4x + 6 is a quadratic polynomial then what is the value of sum of zeroes?
Answers
Answer:
plsss plsss follow me if you like my answer.
Step-by-step explanation:
2x² +4x + 6
dividing the equation by (2) we get,
=> x²+2x +3
= x² +3x-x +3
= x(x+3) -1(x+3)
=(x-1) (x+3)
= x = 1 , -3
here,
a = 2 , α = 1
b = 4 , β = -3
c = 6
sum of zeros = (α+β) = -b/a
=> ( 1 + (-3) = -2
also , -b/a = -4/2 = -2
-2 = -2
hence verified.
