Answer:

x is any integer except for -1

Step-by-step explanation:

If you substitute -1 for x, the denominator value would be 0, or undefined.

For this reason, x cannot be -1, which is mathematically known as an extraneous value.

for the polynomial P(x)=4x^2-5x+6 and c =1, find p(c) by (a. direct substitution and (b. the remainder theorem

nata0808 [166]

$p(x)=4x^2-5x+6$

$c=1\implies p(c)=4(1)^2-5(1)+6=5$

By the remainder theorem, the remainder upon dividing a polynomial $p(x)$ by a linear binomial $x-c$ is equal to $p(c)$ . Via synthetic division, we get

1   | 4   -5   6
.    |        4 -1
- - - - - - - - - - -
.    | 4   -1   5

which translates to

$\dfrac{4x^2-5x+6}{x-1}=4x-1+\dfrac5{x-1}$

or

$4x^2-5x+6=(4x-1)(x-1)+5$

Indeed, when $x=1$ , the first term on the right hand side vanished and we're left with 5.

Answer:

28.57

Step-by-step explanation:

3.14×0.5=1.750

50÷1.75=5000÷175 to eliminate the decimal points

5000÷175=28.571

then we round the answer to the nearest tenths

=28.57
