Answer:

A quadratic equation of the form 0 = ax² + bx + c with a discriminant value of –16 has no real solution

Step-by-step explanation:

A quadratic equation ax²+bx+c=0 with discriminant D=b²-4ac has

2 unequal real solutions if D is positive i.e. D>0

2 equal real roots if D=0

no real root if D is negative i.e. D<0

Here, we are given value of D= -16 which is less than zero

Hence, a quadratic equation of the form 0 = ax² + bx + c with a discriminant value of –16 has no real solution
