Mathematical Equation

  1. Substitution
    Example: x2+2; x=5
    x2+2
    =52+2
    =25+2
    =27
  2. Foil Method
    Example: (x+2)(x+3)=0
    x2+2x+3x+6=0
    x2+6x+6=0
  3. Addition of Functions
    Example: (f+g)(x)=f(x)+g(x)
    Given: f(x)=3x+2; g(x)=4-5x
    (f+g)(x)=(3x+2)+(4-5x)
    (f+g)(x)=3x+2+4-5x
    (f+g)(x)=-2x+6
  4. Subtraction of Functions
    Example: (f-g)(x)=f(x)-g(x)
    Given: f(x)=3x+2; g(x)=4-5x
    (f-g)(x)=(3x+2)-(4-5x)
    (f-g)(x)=3x+2-4+5x
    (f-g)(x)=8x-2
  5. Multiplication of Functions
    Example: (fg)(x)=[f(x)][g(x)]
    Given: f(x)=3x-5; g(x)=x2-2
    (fg)(x)=(3x-5)(x2-2)
    (fg)(x)=3x3-5x2-2x-10

Short Poem

Lady in My Life

Her long black hair blowing in the wind
I slowly kiss her soft black skin
The way she walks hips sway left and right
Got me tossing and turning all through the night

Heart beating fast when she passes by
My mouth shut close cause I'm so shy
She's as pretty as a delicate rose
She stops to take pictures in her standing pose

My skin starts to sweat it's getting hot
She knows I'm staring and she likes it a lot
I slowly walk towards her staring deep into her eyes
To show her I'm her man I"ll leave with a surprise
