Question

How to find the value of X in the equation (x+6)(x+6)=256?

Comments

Solving for X in this equation would be as follows:

1. Move all terms to the left side and set equal to zero.
2. Now set each factor equal to zero.

Your answer:

x = 10,-22

Answer 1

The given equation is ( x+6 ) ( x+6) = 256

In this we can see that it's makes a sense of formula a²+b²+2ab

Like this (x+6)(x+6) we can also write it like this 

     X(x+6)+6(x+6)

     X²+6x+6x+6²

     X²+2×6x+6² now it make sense of a²+b²+2ab and we know that we can also write it like (a+b)²

 So, ( x+6)²=256

  Or, (x+6)=256( square root)

  Or, x+6=16

 Or, x+16-6

So, x= 10.
