Given the polynomial P(x)=x^3-5x+10x-12, is x+3 a factor of P(x)? Explain why. Make sure to show work.

x + 3 is not a factor of the polynomial

Step-by-step explanation:

Using the factor and remainder theorem, if the given expression is a factor, by substituting the value of the expression set to zero , then , we should have 0 as our remaining value after substituting

Set x + 3 to zero

x + 3 = 0

This means;

x = -3

so;

f(-3) = -3^3 -5(-3) + 10(-3) - 12

= -27 + 15 -30 -12

= -54

Since what we have is not equal to zero, then x + 3 is not a factor of the polynomial

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

found it xd it ok yt
