I never knew there was a

Math like this before

Never had someone to show me math

Math like this before

Verse 1

I?m glad that Petro showed me

How to graph equations so I can see

That finding rational zeros can be easy

Polynomials were such a boo hoo

Until Petro showed me how to

Using the rational root theorem was what I had to do

And that?s why I say

Chorus

Verse 2

The leading coefficient is An

The number with the highest exponent

Ao?s the number with no variable yeah, yeah (2x)

Factors of Ao are all in P

Those of An are in q you see

+ or ? p over q are possible zeros

So now I hope you understand

Hatch match ? ch.4 vocabulary

Match the vocabulary terms in Column A to their correct definitions in Column B.

Column a column b

Root A. an inequality of the form

Y >ax + bx +c

Complex number B. any number that can be

Written in the form in the

Form a+bi

Degree C. a solution of the equation

P(x)=0

Polynomial equation D. a shortcut for dividing a

Polynomial by a binomial

Zero E. the variable with the

Greatest exponent

Quadratic inequality F. a value of x for which

f(x)=0

Synthetic division G. a polynomial that is set

equal to zero

Discriminant H. the express under the

radical sign in the

quadratic formula

Who am I ?

Write the proper term to the following descriptions in the space provided.

I?m the formula x = -b + b ? 4ac / 2a, that gives the roots of the quadratic equation of the form ax + bx +c , with a = 0. Don?t you know me by now ? I?m none other than the_________________________________

My name seems a lot more complicated than I really am. I provide a means for dramatically lowering the number of rational values that you might test to find rational roots of a polynomial equation with integral coefficients. My formula is + or ? P over q. I?m the notorious _______________ _______ ___________

I am in the family of complex numbers. That is , combined with my sibling , Real numbers. I can often be the root of a polynomial function. My definition is the form of a + bi where b is not equal to zero and the imaginary unit is i. I?m simply an__________________________

I?m in the quadratic formula . Actually, I?m the expression under the radical sign expressed as b ? 4ac. I am the _____________________ , the one who tells the nature of the roots of the quadratic equation.

MR. RADIAN

There you go again , Mr. Radian!

Constantly making my head spin!

Always making me switch from degrees just for you to your best,

Then almost always making me fail a test!

There you go again , Mr. Radian!

When I?m using you, I don?t seem to win!

? What?s the sine of 90 ??, you consistently ask !

Maybe it?s because you know I?ll barely pass!

There you go again , Mr. Radian!

You really make it hard for me to contend!

? The tangent of 180 is 0!?, you say

But that?s okay because I?m gonna beat you today!!

Here I come again , Mr. Radian!

To quit now would be a sin!

So I?ll try and try , getting help from my friend

Until I have My VICTORY in the end!!!!
