Question

p(x)=4x^2-9x-1 find if x=-2​

Answer 1

Answer:

45

Step-by-step explanation:

Answer 2

Answer:

33

Explanation:

The given Polynomial is ;

p(x) = 4x² - 9x - 1

So, We have to find the value of x = -2

Here, For this We have to substitute the value of x in *Given Polynomial*.

p(x) = 4x² - 9x - 1

P(-2) = 4(-2)² -9(-2) - 1

= 4(4) + 18 -1

= 16 + 18 - 1

= 34 - 1

= 33

Therefore, Value of x is 33.
