- - - - 0^2+2(0)+3
        
        Simplify it to x=3
- - - - -2/2(1)=x
        
        -2/2=x
        
        x=-1
        
        Substitute -1 into x^2+2x+3=0
        
        -1^2+2(-1)+3=y
        
        y=2

- - - - -2/2(1)=x
        
        -2/2= -1
        
        x=-1
- - - - Find values that can multiply to the "c" term and add to the "bx" term- x^2-4x+3
        
        The factors are (x-1)(x-3)
        
        To simplify this, x=1, x=3
    - - Plug equation into calculator- (x^2+2x+3)
      - Find the vertex, y-intercept, and axis of symmetry, then graph it, and locate where the parabola crosses the x axis.
    - - x^2-9=0
        
        Move the nine to the other side of the equation- x^2=+9
        
        Square root both sides- √x= √9
        
        Simplify the equation- x=3
