Determine the value of c for the quadratic expression.
X^2-14x+c
Half of -14 is -7.
The square of -7 is 49.
c=49
A meaningless question.
The value of c can be any real number to have a quadratic expression.
"TheKnowItAll" found the value of c so that the expression becomes a perfect square, but that was not the question.
