#x^2+9x+3# #color(white)("XXXX")#is not a perfect square

#x^2+9x+3# #color(white)("XXXX")#has no Rational factors (as can be verified by checking the discriminant)

To factor a perfect square trinomial ( x^2 + 9x + 3 ), first, determine if it fits the form ( (x + a)^2 ) where ( a ) is a constant. If it does, then the factors are ( (x + a)^2 ). However, in this case, the trinomial does not fit the perfect square form. Therefore, you would use another factoring method such as quadratic formula or completing the square.
