Question

Is -9x²-30x-25 a perfect square trinomial? And if not, is it because of the negative? Please help, giving brainlyest :)

Answer 1

Answer:

  no; because of the factor of -1.

Step-by-step explanation:

  -9x² -30x -25 = -(3x +5)²

The trinomial is a square with an extra factor (-1), so cannot be called a "perfect square trinomial."

Answer 2

Answer:

no

placement of negative signs

Step-by-step explanation:

It is not a perfect square trinomial because of the negative signs in the wrong places.

With the negative signs like this, we do have a perfect square binomial.

9x²-30x+25 = (3x-5)²

9x²+30x+25 = (3x+5)²

The given trinomial has the negative signs in the wrong place to be a perfect square trinomial.
