Question

11.If P(x)=x²-2x+3, then find P(-2).​

Answer 1

Answer:

P(-2) = (-2)^2 -(-2) + 3

== 4 +4 +3

= 11

Step-by-step explanation:

Answer 2

ANSWER:

• P(-2) = 11

GIVEN:

• P(x) = x²-2x+3

TO FIND:

• P(-2)

SOLITION:

P(x) = x²-2x+3

Putting x = (-2) to get P(-2)

=> P(-2) = (-2)²-2(-2)+3

=>P(-2) = 4+4+3

=> P(-2) = 11

If the question asked to find the value of P(-1) then we can do in the above way.

=>P(x) = x²-2x+3

=>P(-1) = (-1)²-2(-1)+3

=>P(x) = 1+2+3

=> P(x) = 6

NOTE:

• In this type of question we have to put the value of x.
• Then simplify the expression and find the value.
• On this way we can solve this question.
