The method of factorization is used to find the roots of a given polynomial. Roots are the solutions of the function. Graphically, these roots are where the curve passes the x-axis. The first step to do is to find the common factor of the equation. That would be x. So you place it outside of the parenthesis.

x³-4x²+45x = x(x² - 4x + 45)

If you solve the quadratic equation inside the parenthesis using the quadratic formula, the roots are imaginary. Therefore, the quadratic equation is already a prime polynomial. 

The final answer is x(x² - 4x + 45).

the measure of one side of a square is (s+3) inches long. which pair of expressions both represent the perimeter of this square?
stich3 [128]
Answer:
perimeter = 4s + 12 inches
perimeter = 4(s+3) inches

Explanation:
We are given that the side length of the square is s+3 inches
In a square, all sides are equal. This means that all four sides are s+3 inches
Now, to get the perimeter, we would add all four sides as follows:
perimeter = s+3+s+3+s+3+s+3 = 4s + 12 inches
For a square, since all sides are equal, we can simply get the perimeter by multiplying the side length by 4 as follows:
perimeter = 4(s+3) inches

Hope this helps :)

The amount of pounds of vegetable needed in fractions to make the stew exactly 10 pounds is 3 3  / 8 pounds

<h3>How to solve fractions?</h3>

The amount of pounds of vegetable needed to make the stew exactly 10 pounds can be calculated as follows:

potatoes weight = 2 7 / 8 pounds = 23 / 8 pounds

green beans weight = 1 1 / 4 = 5 / 4 pounds

pepper weight = 2 1 / 2 = 5 / 2 pounds

Therefore,

weight needed = 10 - 23 / 8 - 5 / 4 - 5 / 2

weight needed = 80 - 23 - 10 - 20 / 8

weight needed = 80 - 53 / 8

weight needed = 27 / 8

weight needed in fractions to make the stew exactly 10 pounds = 3 3  / 8 pounds
