Factorise then following X^2-3x+2

Mathematics
1 answer:
vfiekz [6]3 years ago

(X-2)(X-1)

To do this, first you want to notice that there is no number in front of the x^2.
This will not work on its own if there is

Find 2 numbers that multiply to 2 and add to -3
-3 is in front of the x and 2 is alone in the equation so those are the numbers you are using

-2 and -1 are the only whole numbers that do that
-2 + -1 = -3
-2 * -1 = 2

Which function describes the arithmetic sequence shown<br><br> -1, 1, 3, 5, 7, 9, 11, 13, ...
riadik2000 [5.3K]

Answer:

f(n) = 2n - 3 describes the arithmetic sequence,

-1, 1, 3, 5, 7, 9, 11, 13,.......

Step-by-step explanation:

Function:

A function is like a machine that gives an output for a given input.

A function has an independent variable which is called the input of the function.

The output for a given input is called the dependent variable.

Here. 'n' is the independent variable

f(n) is the function dependent variable i.e function of n as an output.

For Arithmetic sequence

a_{n}= a_{1} + (n-1)d

Where

a_{n} = nth number of the sequence.

a₁ = First term

d = common difference = a₂ - a₁ = a₃ - a₂ = so on

For a function which describes Arithmetic sequence,

a₁ = -1

d = 1 - -1 =2

∴ f(n) = a₁ + (n -1 )d

substituting the values we get

∴ f(n) = -1 +(n-1)2

using distributive property

∴ f(n) = - 1 +  2n - 2

∴ f(n) = 2n - 3  ..........is the required function

2*4w = 40

8w =40

w = 5

l = 3*5 = 15
