Chapter 9.3, Problem 1E
To determine

The sign of the discriminant to predict the nature of equation 3x2+4x7=0.

Introduction: The standard expression of the quadratic equation is ax2+bx+c=0. The value of the disciminant of the quadratic equation is,

b24ac

If the disciminant is negative number, then the roots of the equation are not real numbers and there is no real solution of the equation.

If the discriminant is positive then two condition are possible,

If b24ac is a perfect square, the two real number solutions are rational numbers,

If b24ac is not a perfect square, the two real number solutions are irrational,

If the discriminant is equal to 0, there is one real number solution to the equation.
