difference of squares formula trinomial
What is the trinomial square rule?
Perfect Square Trinomial Formula
A trinomial is said to be a perfect square if it is of the form ax2+bx+c and also satisfies the condition of b2 = 4ac.
There are two forms of a perfect square trinomial.
They are, (ax)2+ 2abx + b2= (ax + b)2----- (1)The Difference of Two Squares theorem tells us that if our quadratic equation may be written as a difference between two squares, then it may be factored into two binomials, one a sum of the square roots and the other a difference of the square roots.
This is sometimes shown by the expression A² - B² = (A + B) (A - B).
