Therefore, if a trinomial is of the form ( x) 2 + 2( x)( y) + ( y) 2, it can be factored into the square of a binomial.
Example 1: Is 4 x 2 – 20 x + 25 a square trinomial? If so, factor it into the square of some binomial. 4 x 2 = (2 x) 2 and 25 = (–5) 2 and –20 x = 2(2 x)(–5)So it is a square trinomial, which factors as follows.4 x 2 – 20 x + 25 = (2 x – 5) 2
