Answer 6

How can you tell when a quadratic equation has no real solutions? (1 point)

When the radicand is negative
When b in the quadratic formula is greater than the radicand
When the radicand equals zero
When the radicand is not a perfect square

Answer 7

give me a minute this is hard stuff 0.0

Answer 8

A First one

Answer 9

When the radicand is negative then you know the equation has no real solutions. This is because you CAN'T find the square root of a negative number. If the radicand is a perfect square it will have 2 rational solutions (rational because they terminate) If it is NOT a perfect square it will have 2 irrational solutions(irrational because they do NOT terminate) Lastly, if the radicand is zero, then ther is only one solution...zero.
I hope this is helpful!
