Who invented math and how do we know he's right?

Euclid introduced the axiomatic method still used in mathematics today, consisting of definition, axiom, theorem, and proof.

Step-by-step explanation:

Pythagoreans

Step-by-step explanation:

The Pythagoreans who made up the term 'mathematics', and the study of math began with them. The Pythagoreans are given credit for the first proof of the Pythagorean theorem, though the theorem has a long history, and with proof of the existence of irrational numbers.

Pythagorean Theorem: a^2 + b^2 = c^2

Say a = 3 and b = 4.

3^2 is 9

4^2 is 16

9 + 16 is 25

The root of 25 is 5

So, 3^2 + 4^2 = 5^2

(This is just an example)

Hope this helped :)

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
