for p(x)= 192 + 21x^3 + 54x^2 - 3x^4 - 264x, use synthetic substitution to evaluate p(1), p(-2), and p(8)
RSB [31]

The value of p(1), p(-2), and p(8) is 0, 744 and 0 respectively

<h3>What is polynomial function?</h3>

Given the function p(x)= 192 + 21x^3 + 54x^2 - 3x^4 - 264x

We are to get the following parameters:

p(1)= 192 + 21(1)^3 + 54(1)^2 - 3(1)^4 - 264(1)\\p(1)=192+21+54-3-264\\p(1)=0

For p(-2)

p(-2)= 192 + 21(-2)^3 + 54(-2)^2 - 3(-2)^4 - 264(-2)\\p(-2)=192-168+216-24+528\\p(-2)=744

For p(8)

p(8)=192 + 21(8)^3 + 54(8)^2 - 3(8)^4 - 264(8)\\p(8)=192+10,752+3,456-12,288-2,112\\p(-2)=0

Hence the value of p(1), p(-2), and p(8) is 0, 744 and 0 respectively

Look at the following numbers:
jok3333 [9.3K]

Answer:

The correct answer is: -7, 7

Step-by-step explanation:

Given numbers are:

-7, 0, 7, 14

We have to check all pairs of numbers with respect to sum to check that which pair of numbers sums up to zero. So first of all, we will take -7 and will find its sum with other numbers.

So,

-7+0 = -7\\-7+7=0\\-7+14 = 7

We can see that the sum of -7 and 7 is zero.

Hence,

The correct answer is: -7, 7
