Question

if P (x) = 4x^5- 3x- 5x^3 + x^2-8 then find P (-1)​

Answer 1

ANSWER:

• Value of P(-1) is (-3)

GIVEN:

• P(x)= 4x⁵-3x-5x³+x²-8

TO FIND:

• Value of P(-1)

SOLUTION:

P(x)= 4x⁵-3x-5x³+x²-8

Putting x = (-1) in P(x)

P(-1) = 4(-1)⁵-3(-1)-5(-1)³+(-1)²-8

P(-1) = 4(-1)+3+5+1-8

P(-1) = -4+9-8

P(-1) = -12+9

P(-1) = (-3)

Value of P(-1) is (-3)

NOTE:

• This type of question can be solved by putting the values in place of x.
• In this question it is asked to find the value of P(-1) then we will put (-1) in place of x.
• In this way we can solve this problem.
