Sagot :

Correct Answer: A and F!!

A- 3x^2+ 5x + 10=0

F- 2x^2 + 12 = -9x

Step-by-step explanation: Just did it and it’s right, hope that helped!! :)

The equations that have two complex solutions are 3x^2 + 5x + 10 = 0 and 2x^2 + 12 = -9x

For a quadratic equation to have a complex solution, hence the discriminant must be less than zero.

The discriminant is expressed as:

D = b^2 - 4ac

For the equation 10x^2 - 10 = 0

D = 0^2 - 4(10)(-10)

D = 400

Option B is false.

For the equation 3x^2 + 5x + 10 = 0

D = 5^2 - 4(3)(10)

D = 25 - 120

D = -95

Since D < 0, hence the equations 3x^2 + 5x + 10 = 0 have two complex solutions

For the equation 2x^2 + 12 = -9x

D = 9^2 - 4(2)(12)

D = 81 - 96

D = -15

Since D < 0, hence the equations 2x^2 + 12 = -9x have two complex solutions
