Answer 1

Answer:

Step-by-step explanation:

5x-4x²+3

p(-1)= 5(-1)-4(-1)²+3

-5-4(1)+3

-5-4+3

= -6

Answer 2

Question :

Find the value of the polynomial 5x³ - 4x² + 3

Given :

The value of x = -1

Let us substitute the the value of x in the given polynomial.

We get,

5(-1)³ - 4(-1)² + 3

⇒ -5 - 4 + 3

⇒ -9 + 3

⇒ -6.

Hence the value of the given polynomial is -6.
