Question

P of x is equal to x square - 5 x + 6 then P (3)

Answer 1

Answer:

Step-by-step explanation:

p(x)=x^2-5x+6

p(3)=(3^2)-5(3)+6=9-15+6=0

Answer 2

ANSWER

• P(3) = 0

GIVEN:

• p(x)= x²-5x+6

TO FIND:

• P(3)

SOLUTION:

=> P(x) = x²-5x+6

Putting x = 3 in P(x) we get:

=> p(3)= (3)² -5*3+6

=> P(3) = 9-15+6

=>P(3)=15-15

=>p(3) = 0

This shows that 3 is the zero of P(x).

If the question ask to find the value of P(2) then :

=> P(x) = x²-5x+6

=> P(2) = (2)²-5*2+6

=> P(2) = 4-10+6

=> P(2) = 0

NOTE:

• This type of question can be solved by putting the value in place of x .
• Then simplify the expression and find the value.
• In this way we can solve this question.
