Explain what value or values of c make the equation x^2+12x+c=0 have 1 and only one solution (please justify the answer) Thanks so much!!
only one solution means thtat it factors to a perfect square
to do that, we do
the number in front of the x^2 is 1
then take 1/2 of the number in front of the x term and square it and that is the constant term
