Six times a number, increased by 3 is is 27. find the number

Answer : The number is 4.

Step-by-step explanation:

Given :

six times a number, increased by 3 is is 27.

To Find:

The number.

Solution :

Let the number is x

six times a number is 6x

Increased by 3 = 6x+3

According to the given question :

Solving the value x :

6x+3 =27

6x = 27-3

6x = 24

x = 24/6

x = 4

Hence, the number is 4.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
