Provide an appropriate response.Solve the equation
for x. If y is positive and b is negative, what, if anything, can you determine about the signs of the solutions? Explain your reasoning.
What will be an ideal response?
or
. Since b is negative, the first term in the numerator is positive. Since y is positive, the radicand is greater than b2 and the square root is, thus, greater than -b. Therefore, the sign of the first solution is positive and the sign of the second is negative.
