Answer 1

Answer:

89

Explanation:

this is the answer okkkkkk

Answer 2

Answer:-

x2 + 4x + 5 = 0.

Here, a = 1, b = 4, c = 5.

So,

→ √b2 – 4ac = 0.

→ √16 – 4×1×5

→ √16 - 20

→ – 4.

→ – 4 < 0.

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.
