Question

find the value of p（x）=x²-5x+4 at x= -1​

Answer 1

Answer:

10

Step-by-step explanation:

p(-1)= (-1)²- 5(-1)+ 4

p(-1)= 1+ 5+ 4

p(-1)= 10

Answer 2

Answer:

Value of x at x = -1 is 10

Step-by-step explanation:

Procedure:

Here we have been given the value of polynomial involving x. The question is about finding the value of this polynomial at x = -1. So, just substitute the value of x as -1.

Solution:

p (x) = x² - 5x + 4

When the value of x is taken as -1,

p (-1) = (-1)² - 5(-1) + 4

→ p (-1) = 1 + 5 + 4

→ p (-1) = 6 + 4

→ p (-1) = 10

∴ The value of x = -1 is 10
