Question

find the value of polynomial 5x - 4x²+ 3 at x=1​

Answer 1

Answer:

The value of x is 1.

Given polynomial :- 5x - 4x^2 + 3

By putting the value of x, we get

5(1) - 4(1)^2 + 3 = 5 - 4 + 3 = 5 - 1 = 4

Hence, the value of the given polynomial is 4.

Answer 2

Answer:

The value of the polynomial at $x=1$ is 4.

Step-by-step explanation:

In context to the question asked,

We have to find the value of the polynomial at $x=1$ or P ( 1 )

As per data given in the question,

The given polynomial,

$P ( x ) = 5x - 4x^2+ 3$

Now, by plugging the value of x as 1:

=> $P(x) = 5x - 4x^2+ 3$

=> $P ( 1 ) = 5 ( 1 ) - 4 ( 1 ) ^2 + 3$

Simplifying it further, we get

=> 5 - 4 + 3

=> 4

Hence, the value of polynomial at $x=1$ is 4.
