Question

Find the value of polynomial 4x²

-3x+7 at x = –1 step by step ​

Answer 1

Answer:

14

Step-by-step explanation:

By putting the value of x= -1 in the given equation,we get:-

4( - 1)^2 - 3( - 1) + 7

= 4 + 3 + 7

= 14

Answer 2

Answer:

The value of polynomial 4x² - 3x + 7 at x = -1 is 14.

Step-by-step explanation:

We need to put the value of x as -1.

f(x) = 4x² - 3x + 7

⇒ f(-1) = 4(-1)² - (3 * -1) + 7

⇒ f(-1) = 4 + 3 + 7

⇒ f(-1) = 14

∴  The value of polynomial 4x² - 3x + 7 at x = -1 is 14.
