What polynomial identity will prove that 49 = (2+5)^2? (a. difference of squares; b. difference of cubes; c. sum of cubes; d. square of a binomial)

Option D is correct.

Square of binomials.

Step-by-step explanation:

Prove that:

Square of binomials states that the square of a binomial is always a trinomial.  

Also, it will be helpful to memorize these patterns for writing squares of binomials as trinomials.

Take RHS

Apply the square of binomial, we have;

                   = 4 + 20 + 25 = 24 + 25 = 49 = LHS           proved.

Therefore, Square of binomials identity will prove that
