Question

Solve the following quadratic equation
5m² + 2m + 1 = 0​

Answer 1

Answer:

The roots of the given quadratic equation are

m=√-16/10, m= -√-16/10

Step-by-step-explanation:

NOTE : Kindly refer to the attachment first.

The given quadratic equation is

5m² + 2m + 1 = 0

Comparing with ax² + bx + c = 0, we get,

a = 5, b = 2, c = 1

Now,

b² - 4ac = ( 2 )² - ( 4 × 5 × 1 )

∴ b² - 4ac = 4 - 20

∴ b² - 4ac = ( - 16 )

Now, by using formula for quadratic equation, we get,

the roots of the given quadratic equation are:

m=√-16/10, m= -√-16/10
