The equation given is,
The factor of the equation is obtained as,
In the equation given , two numbers 2 and 28.
We have to find the GCF which is greatest common factor of the two numbers,
The only number common from the two numbers factor are, 2.
And also when we open the bracket , we take 2 common for simplify the equation.
Therefore , the factor of the given equation is 2.
Hence verified from both sides.
