Answer:

The only one

Step-by-step explanation:

The one that is shown has a negative b^2-4ac value.

We know this because the function has no real roots -> that means that they must be complex, which can only occur if b^2-4ac < 0

Which equations have no real solution but have two complex solutions?
Sidana [21]

Answer:

Since we cannot find the square root of a negative number (at least not using the real number system), we cannot evaluate the formula any further. There will be no solutions. Use the discriminant to determine whether the quadratic equation has two, one, or no solutions. The result is a negative number. i really hope this helps u. good luck my dude

Evalute the experssion -280+12x=
Alina [70]
The answer is 23 1/3. First, you need to add 280 to both sides of the equations in order cancel out 280 and get 12x by itself. But remember whatever you do to one side of an equation, you must to do the other. So now you have 12x=280. Now divide both sides of the equation by 12 in order to get x completely isolated. 280 divided by twelve is 23 1/3.
