For this case we have the following equation:
 (3x + 4) ^ 2-36 = 15x + 20
 We can rewrite the equation:
 (3x + 4) ^ 2-36 = 5 (3x + 4)
 Now we define the following variable:
 p = 3x + 4
 Substituting the variable in the equation we have:
 p ^ 2-36 = 5p
 Rewriting:
 p ^ 2 - 5p - 36 = 0
 Answer:
 An equation that is equivalent in terms of p is:
 p ^ 2 - 5p - 36 = 0
