Find the missing term, so that the expression forms a perfect square trinomial.
» To identify the other terms of a perfect square trinomial, we already know that the twice of the square root of the first and third term is the second term. Make equation and represent x, y, and z as the first, second, and third term respectively to make you understand.
For my answers, let 'w' be the missing term aka the blanks that should be answered.
