What is the discriminant of -x² + 2x + 12 = 0 ?

In the quadratic formula,

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 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**
