Answer: When two polynomials are multiplied, the product is always a
polynomial.
Step-by-step explanation:
The only true property for polynomials is the third options because when you do multiply polynomials, you can only get a polynomial.
For instance;
Multiply (5x – 6y) by (7x – 4y)
= (5x – 6y)(7x – 4y)
= 35x² - 20xy - 42xy + 24y²
= 35x² - 62xy + 24y²
The result is a polynomial.
The rest of the options will not always yield polynomials.
If your quadratic function has x intercepts of 4 and -3, that means that the points are (4, 0) and (-3,0), or the values x has when y=0. Since your quadratic (which represents y) must then equal 0, then your factors of that equation would potentially equal 0 as well. That means that if x=4, then subtract 4 from each side to get x-4=0, and so one factor is (x-4) Similarly your other factor would be (x+3).

<span>(x-4)(x+3)=0 </span>
<span>x^2-x-12=0</span>

A perfect square factor of each of the given number on the left will be matched as:
126 ---> 9
192 ---> 16
112 ---> 16
245 ---> 49
75 ---> 25
162 ---> 9
<h3>What is a Perfect Square?</h3>
- A perfect square can be described as a special number which can be squared.
- Squared numbers are numbers that are gotten by multiplying a number by itself.
- For example, square of 25 is 5 (5×5). This means that 25 is a perfect square.
<h3>What is a Factor of a Number?</h3>
- Factors of a number can divide the number with no remainder.
- For example, 5 is a factor of 25, because 25/5 = 5.
Therefore, a perfect square factor of each of the given number on the left will be matched as:
126 ---> 9
192 ---> 16
112 ---> 16
245 ---> 49
75 ---> 25
162 ---> 9
