Question

The difference of the square of a number and 4 is equal to 3 times that number. Find the positive solution.

Answer 1

Let the number be 'a':

The difference of the square of a number and 4

a^2 -4

is equal to 3 times that number.

= 3*a

a^2 -4 =3a

a^2 -3a -4=0

(a-4) (a+1)=0

solutions are: 4 and -1

Answer 2

The positive solution to the question will be 4 and -1

What is an equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Let the number be 'a'

The difference between the square of a number and 4.

=  a²  -  4

And is equal to 3 times that number.

= 3  x  a

a²  -  4    =    3a

a²  -   3a   -  4   =   0

(   a  -  4   ) (   a  +  1  )  =  0

solutions are: 4 and -1

Therefore the solution to the question will be 4 and -1
