Question

x²+4x-5=0 find root ​

Answer 1

Answer:

Using the quadratic formula. a = 1, b = 4, c = 5. So, b2 – 4ac = 16 – 20 = – 4 < 0.

Step-by-step explanation:

Since the square of a real number cannot be negative, therefore √b2-4ac not have any real value. So, there are no real roots for the given equation.
