It can be factored as the SQUARE OF A BINOMIAL
A trinomial is perfect square if it can be factored into the form
22y2-31y+9 = (22y-9)(y-1) when factored
(y10 + 2y5z3 + 4z6)
The constant term of the trinomial
It is the constant term of the trinomial.
A trinomial of the form ax2 + bx + c is a perfect square if (and only if) b2-4ac = 0 and, in that case, it is factored into a*(x + b/2a)2
30x2-23x-14 = (6x-7)(5x+2) when factored with the help of the quadratic equation formula
[ x3 + 3x2 + 2x ] is a trinomial. It's factors are [ x, (x + 1), (x + 2) ] .
prime
x2-18x+81 = (x-9)(x-9) when factored
Math books and teachers will make it look like all trinomials can be factored, but many are not.
