I hope this helps you :)

Step-by-step explanation:

given that: also its being said that: it has no solutionthus shall we use the formula: b²-4ac < 0

Extra's:

when it has solution:  b²-4ac > 0 when has only one or equal use:  b²-4ac = 0when it has no solution or real numbers:  b²-4ac < 0

Now lets solve:

using b²-4ac < 0:
