A trinomial is perfect square if it can be factored into the form
the 5 kinds of factoring are common monomial factor, difference of two cubes, quadratic trinomial, perfect square trinomial,and difference of two square.
It can be factored as the SQUARE OF A BINOMIAL
A perfect trinomial must be of the form a2x2 Â± 2abxy + b2y2 and this factorises to (ax Â± by)2.
(x + 3)(x + 3)
A trinomial is perfect square if it can be factored into the form (a+b)2 So a2 +2ab+b2 would work.
(p - 9)(p - 9)
perfect trinomial square?? it has the form: a2 + 2ab + b2
Write it in the form ax2 + bx + c. It is a perfect square if b2 = 4ac
A perfect square trinomial is looking for compatible factors that would fit in the last term when multiplied and in the second term if added/subtracted (considering the signs of each polynomials).* * * * *A simpler answer is: write the trinomial in the form ax2 + bx + c. Then, if b2 = 4ac, it is a perfect square.
