Polynomials can have REAL ZEROS or COMPLEX ZEROS. Real Zeros to a polynomial are POINTS where the graph crosses the x-axis when y=0. When we graph each function, we can see these points. Complex Zeros are the SOLUTIONS of the equation that ARE NOT VISIBLE on the graph.

Based on the diagram, which is a true statement?
trapecia [35]

Based on the diagram, the true statement is "If a student is an honor student, then he/she may also be a band member."

<h3>What does the diagram show?</h3>

What two numbers add up to 10 and multiply to 21
WITCHER [35]

Answer:The answer is 3 & 7

Step-by-step explanation:3 x 7 = 21

3 + (7) = 10

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x2 + 10x + 21 = 0

If so, the solution to factor the quadratic equation above is:

(X + 3 ) (X + 7)

To summarize, since 3 and 7 multiply to 21 and add up 10, you know that the following is true:

x2 + 10x + 21 = (X + 3 ) (X + 7)

Sum of x and it’s square is equal to y times z
ludmilkaskok [199]

The algebraic representation of the statement is x + x² - yz = 0

<h3>What are algebraic expressions?</h3>

Algebraic expressions brings the idea of creating or expressing numbers using letters or alphabets without specifying their actual values.

From the information given , we have that;

  • sum of x and it's square = x + x²
  • Equal to y × z

Now, let's equate the expressions;

x + x² = y × z

x + x ² = yz

Let's make into quadratic form

x + x² - yz = 0

Thus, the algebraic representation of the statement is x + x² - yz = 0
