6. If x + 2 is the only factor of the polynomial P(x),then P(2) is: Options:
A. Cannot be determined
B. Not Zero
C. R(2)
D. Zero

B

Step-by-step explanation:

If (x + h) is a factor of a polynomial f(x) then f(- h) = 0

Here (x + 2) is a factor of P(x), thus

P(- 2) = 0 but P(2) ≠ 0 → B

go on the tube you might find some information there

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
