This fits the standard identity a square + 2ab + b square. The first term is the square of 7g and the last is the square of h, which yields the grouped factor (7g + h) square.

This algebraic expression can be factored by identifying the perfect square components. The first part of the expression is 49g square, which is equal to (7g) square. The last part is h square, which is equal to (h) square. The middle value 14gh is exactly two times 7g times h. Since it matches the standard addition identity completely, it condenses into the final perfect square binomial factor (7g + h) square.
