the
Determine the nature of the roots
equation, 5x²-2root3x -7=0
​

Answer 1

Step-by-step explanation:

5x²-2√3x-7=0

√(b²-4ac)

√((-2√3)²-4(5)(-7))

√(12+140)

√152

Roots are irrational

Answer 2

Answer:

The roots are real and distinct

Step-by-step explanation:

In the above equation

a=5, b=(-2√3), c= (-7)

Therefore, using the discriminant formula:

=b^2-4ac

=(-2√3)^2 - 4*5*-7

=152

Since, D<152 the roots are real and distinct
