If (x-2) is a factor of P(x), then what do you think P(x) will be if x = 2? If x is 2 then won't x-2 be zero? And if a factor of of P(x) is zero, won't P(x) be zero, too (regardless of what the other factor is)?
So the "proper value" to test is x=2. If P(2) = 0 then x-2 must be a factor and if P(2) is not zero then x-2 is not a factor is
.3x-x+2=4
I'll leave it up to you so simplify this and find out if x-2 is a factor.
P.S. As I indicated above you use P(2) to see if (x-2) is a factor. P(-2) checks to see if (x-(-2)) or (x+2) is a factor. P(-2) does not check for a factor of (x-2)! Please redo the problem and see what P(2) works out to be!

Step-by-step explanation: Sorry if i got it wrong
Step-by-step explanation:
<u>Given:</u>
- Investment P₁ = $3670
- Investment P₂ = $2040
- Rate of interest r₁ = 1.9% SI
- Rate of interest r₂ = 5.5% SI
- Time t = 5 years
<u>Find amount of interest in both investments:</u>
- I₁ = P₁r₁t = $3670*(1.9/100)*5 = $348.65
- I₂ = P₂r₂t = $2040*(5.5/100)*5 = $561.00
<u>As we see the</u><u> online savings account</u><u> earns more interest and the difference is:</u>
- $561.00 - $348.65 = $212.35 ≈ $212

Answer:
-28
Step-by-step explanation:
20x+12y-28=20x+12y+[?
subtract like term so 20x-20x and 12y-12y
therefore -28 =[?
