Answer with explanation:

→Consider a Polynomial

   \rightarrow ax^n+bx^{n-1}+cx^{n-2}+...........+d

→We will use rational root theorem to find out the factors of the polynomial.

  \rightarrow ax^n+bx^{n-1}+cx^{n-2}+...........+d\\\\\rightarrow a(x^n+\frac{bx^{n-1}}{a} +\frac{cx^{n-1}}{a}+..........+\frac{d}{a})

→Factors of d are

        =\pm 1 , .....\pm d\\\\ \text{Factors of a are}=\pm 1,.....\pm a\\\\ \pm\frac{d}{a}  

⇒Now,substitute these integers that is factors into Polynomial expression to find which expression is equal to Zero.These integers will be factor of Polynomial expression.

For example

 f(x)=x²-3 x+2

By rational root theorem ,roots of the polynomial can be , -1,1,2,-2.

f(1)=1²-3×1+2

   =1-3+2

   =0

f(2)=2²-3×2+2

   =4-6+2

  =0

So, 1 and 2 are root of the polynomial expression.

Step 1: If there is a common factor, factor out the GCF. Step 2<span>: Identify the number of terms: (i) If polynomial has two terms, convert polynomial into difference of two squares or sum of two cubes or difference of two cubes.</span>

If a gallon of milk costs $5.25 now and the price is
adelina 88 [10]

Answer: It will take approximately 21 years.

Step-by-step explanation:

6 percent of 5.25 is 0.315 (5.25 x 0.06 = 0.315)

Then you subtract 5.25 from 12 to calculate the number of years. (12 - 5.25 = 6.75)

Divide 0.315 from 6.75 (6.75 / 0.315 ≈ 21.4)

Use counters to model two integers with different signs whose sum is positive.Explain how you know the sum is positive.
Dvinal [7]
if you add two numbers with different sign , but absolute value of positive number is greater than absolute of negative number , sum will be positive  ex. -4+7=3 I7I GREATER THAN I-4I,   WE SUBTRACT 4 FROM 7 =3    POSITIVE  OR -14 +20 =6 POSITIVE , ABSOLUTE VALUE OF 20 GREATER THAN ABSOLUTE VALUE OF -14
