solving quadratic equations

Example

above is a quadratic equation. it is when you make an input output box. here is an example below

the rule is: 9*4+x^3=y and n=4. when you solve one you replace x with 4

                    9*4+4^3=?

then you remember,PEMDAS but only the e. so then it is 9*4+64. then the m. so then it is 36+64=100

THE ANSWER IS A COINCEDINCE!!!

really it is here is another; 9*4+x^3 and make it 9*4+5^3 the same thing pEmdas so it is 9*4+125

then it is 36+125=161

another is 9*4+6^3 i know, no variable. so it is 36+216=252 see the interval? that is what makes it a quadradic equation, not linear 

now i hope you know more about quadratic equations

Solving simple equations

Example

This scale is perfectly balanced.  This means both sides are the same.

Lesson

(__x+32__|__56___)

1.first you inverse the first number isolating the variable.

        -32         -32

2.then you subtract the same from the second number

 (__x+32__|__56___)

        -32         -32

         x+0        24    x=24

3.then the answer to the second side is the answer

Now I hope you know more about solving simple equations

           adding and subtracting decimal with common and unlike denominators and justify your solutions using manipulativea and mathimatical reasoning

Examples

         6/7 +  2/5 = 44/35 or 1 9/35

        /     \     |   \

        30/35+14/35= 44/35 or 1 9/35

         |         /        _/

        30+14=44 the denominator stays 35

       8/9 +7/9=15/9 or 1 6/9

          \      |

             8+7=15

Lesson

        To find the sum of 2 fractions you first find the LCD or the least common denominator.  Next, you multiply the numerator by the same number you multiplied the denominator to get the fractions. Then, you add the numerators to get the sum.  Last, (you may not have to do this.) simplify the fraction to get a mixed number.  If the denominaters are the same, add the numerators and you then simplify.

use strategies to make ways to find ways to find the circumfrence or circles

example problem

pi: π=c/d = 3.14 or π or 22/7=π . how to find the circumfrence of the circle from diameter: d of circle *π=c

lesson

    to find the circumfrence of a circle you multiply the diameter by pi or π. to find the diameter you divide the circumfrence by π
