Question

If zero
of P(x) =
2x³- 4x² + 5x + a is 1 Then find a​

Answer 1

Answer:

put values of x as 1

as 1 is the zero of the polynomial

3+a= 0

a= -3

Answer 2

Answer:

-3

Step-by-step explanation:

Given P(1)=0

P(x)=2x^3-4x^2 + 5x +a

Therefore,

2(1)^3 - 4(1)^2 +5(1) +a =0

2-4+5+a=0

-2+5=-a

-a=3

a=-3
