Question

Evaluate P(×)=2-ײ solution

Answer 1

P(x)=2-x^2=0

=>-x^2=-2

=>x^2=2

=>x=+_√2

=>x=+√2,x= -√2

Answer 2

Answer:

x= √2 is your answer

Step-by-step explanation:

Given :- P(x) = 2-x². -------------[ equation 1]

let , P(x) be equal to zero, so

P(x) = 0

2-x²=0 ( from equation 1)

-x²=0-2

-x² = -2

x² =2. ( - sign is both side , which can cancelled)

x= +√2

x= +√2
