## How do you solve quadratic equations with complex numbers?

Quadratic equation as, ax2+bx+c=0 a x 2 + b x + c = 0 where a,b,c are complex numbers and a≠ 0. (i) if D = b2 – 4ac = 0 then the roots are complex and equal. (ii) if D = b2−4ac≠ b 2 − 4 a c ≠ 0 then complex but unequal roots.

### Does the quadratic formula work for complex numbers?

The quadratic formula works regardless of whether the coefficients are real or complex.

**Which equation shows the quadratic formula correctly to solve 7x?**

Therefore, the quadratic formula used correctly to solve 7×2 = 9 + x for x is x=1±√25314 x = 1 ± 253 14 .

**What is the discriminant of 3x 2 10x 2?**

The discriminant of is 76. Here, a=3, b=-10 and c=2. Substitute the values, Therefore, the discriminant of is 76.

## What is the discriminant of 9x 2 10x?

Which equation has the solutions? What is the discriminant of 9×2 + 2 = 10x? If x = -3 is the only x-intercept of the graph of a quadratic equation, which statement best describes the discriminant of the equation? The discriminant is 0.

### Which equation shows the quadratic formula used correctly to solve 5x squared plus 3x minus 4 equals 0 4x?

Answer: The equation that shows the quadratic formula is used correctly to solve 5×2 + 3x – 4 = 0 for x is x = [-3 ± √{32 − 4 × 5 × (-4)}] / (2 × 5) and the values of x are (-3 + √89)/10 and (-3 – √89)/10. Let’s look into the solution below.

**What is the discriminant of the quadratic equation 3 4x =- 6×2?**

– 56

The given quadratic equation is 3 – 4x = -6×2. The standard quadratic equation is the form ax2 + bx + c= 0. Therefore, the discriminant of the quadratic equation 3 – 4x = -6×2 is – 56.

**What is discriminant of 9×2 2 10x?**

## What is the discriminant of the quadratic equation 3 4x 6×2 68 56?

The standard quadratic equation is the form ax2 + bx + c= 0. Therefore, the discriminant of the quadratic equation 3 – 4x = -6×2 is – 56.

### What is the discriminant of 3x 2/10 =- 2?

**What is discriminant of the quadratic equation 3 4x =- 6x 2?**

-56

The discriminant of the quadratic equation 3 – 4x = -6×2 is -56.
