Answer:

$x = 0$

Step-by-step explanation:

Given

Represent the number with x.

So:

$2 + x + x + x + x + x + x + x + x + x + x = 2$

$2 + 10x = 2$

We want to solve for x

Subtract both sides by 2

$2 - 2 + 10x = 2 - 2$

$10x = 0$

Solve for x

$x = \frac{0}{10}$

$x = 0$

No other number aside 0, satisfy the property.

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30

Natasha_Volkova [10]

Answer:

P(2)=0 then x-2 is a factor of P(x)

Step-by-step explanation:

To see if (x-2) is a factor just plug in 2 for x into the polynomial expression.

2(2)^3-3(2)^2-17(2)+30

2(8)-3(4)-34+30

16-12-34+30

4-34+30

-30+30

Since P(2)=0 then x-2 is a factor
