Question

is -1 zero of polynomial 2x^2+4x+3=0​

Answer 1

Answer:No

Step-by-step explanation:2×1+ 4×(-1) +3 = 2 - 4 + 3 = 1

Answer 2

Step-by-step explanation:

for checking this just put the value of zero as x

so

2(-1)^2 + 4(-1) +3=0

2(1) -4 +3=0

2-4+3 =0

1 =0

this is not equal so (-1) is not a zero of given polynomial
