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

Write it in the form ax2 + bx + c. It is a perfect square if b2 = 4ac
What value, in place of the question mark, makes the polynomial below a perfect square trinomial?x2 + 12x+ ?
false!
