Question

Find whether the following equations have roots. If real roots exits , find them.
4x^2 - 1/5x + 1/32 = 0

Answer 1

Answer:

first find discriminate

d=b^2-4ac

d=(5√5)^2-4×1×(-70)

d=125+280

d=405

therefore d is positive

it have real roots

Step-by-step explanation:

Answer 2

Step-by-step explanation:

D=b2-4ac/2a

=(‐1/5)²‐4*4*1/32

=1/25‐1/2

=2‐25/50

=‐23/50

now D<0

hence , the given equatio has no real roots.
