Question

z²+ z + 1/4

Evalute this following​

Answer 1

Answer:

z=-1/2 and z=-1/2

Step-by-step explanation:

z²+z+1/4=0

Now by LCM

4z²+4z+1=4×0

4z²+4z+1=0

Now by using Quadratic formula

a=4

b=4

c=1

-b±√b²-4ac/2a

-4±√(4)²-4(4)1/2(4)

-4±√16-16/8

-4±√0/8

So, z=-4/8 and z=-4/8

Therefore, z=-1/2 and z=-1/2
