An equation is a relationship between two or more variables expressed in equal to sign. It is solved to find the value of variables. Equation of two variables will look like ax+ by=c.
Let the required number be x.
According to question we have to form an equation which will be:
4[tex]x^{2}[/tex]=12x
[tex]4x^{2} -12x=0[/tex]
4x(x-3)=0
4x=0, x-3=0
x=0, x=3
Non negative number=3
Hence 3 is the number whose 4 times square is equal to 12*3.
