Chorus
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!!!!
