WebPerfect Square Trinomials Pattern If a and b are real numbers a2 + 2ab + b2 = (a + b)2 a2 − 2ab + b2 = (a − b)2 To make use of this pattern, you have to recognize that a given trinomial fits it. Check first to see if the leading coefficient is a perfect square, a2. Next check that the last term is a perfect square, b2. WebIn the case of a perfect square, the middle term is the first term multiplied by the last term, and then multiplied by 2 2. In other words, the perfect square trinomial formula is: a^ {2} …
