Mathematics cheat sheet will help you and to be more informed about the formulas. Knowing it will be your guide.

## mathematics Cheat Sheet Template Algebra for you

- (x+y)2 = x2 + y2 + 2xy
- (x-y)2 = x2 + y2 – 2xy
- (x+y)3 = x3 + y3 + 3xy(x + y)
- (x-y)3 = x3 – y3 – 3xy(x – y)
- x2 – y2 = (x + y)(x – y)
- x-2 = 1/x2, 2-4 = 1/16 = 1/24
- (xa)(xb) = xa+b
- xa/xb = xa-b = 1/xb-a
- x0=1
- xaya = (xy)a, 2232 = 62

**The quadratic equation**, for any given x if ax2 + bx + c =0 then x has the 2 solutions

x=(-b+√(b2 – 4ac)/2a, x=(-b-√(b2 – 4ac)/2a

xayb is not equal to (xy)a+b

**Functions:** f(x)= 9x + 5; where f is the function of x because it will change X, depends on the X.

Value of the f can be obtained by the substituting x in ‘9x + 5’, so f(2) =23 when x=2. The domain of any of the function is set of permissible inputs values of variable. For example:

-3x + 5 < 23

for the above inequality, you need solutions for x. Above equation is the equivalent to -3x < 18 or -x < 6 which means x > -6

hence x can be -5,-3.. 1,2… (infinite values)

**Polygons:**

, where the n = # of sides

**Prime Numbers and the Integers:**

1 is not the prime. 2 is the smallest number for prime and the only even prime.

An integer is any counting number which include the negative numbers (e.g. -3, -1, 2, 7…but not 2.5).

**Fast Fractions:**

**Divisibility:**

sum of the digits will be divisible by three

last 2 digits of the number will be divisible by four

last digit is either a five or zero

even number and the sum of the digits will be divisible by three

if last 3 digits will be divisible by eight

sum of the digits will be divisible by nine

**Combination and the permutations:**

n will be the total number, r will be the number you choose

**Probability:**
