What is the discriminant of x² + 2x + 12 = 0 ?
In the quadratic formula, the discriminant is b²  4ac, the part under the square root sign.
a is the coefficient of x² b is the coefficient of x c is the constant term In x² + 2x + 12, a = 1, b = 2, and c = 12 b²  4ac {the discriminant} = 2²  4(1)(12) {substituted into the discriminant} = 4 + 48 {multiplied} = 52 {added} the discriminant is 52 Ask the House
