Question

factorise it a^2 + a + 1/4​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

(a+1/2).(a+1/2)

Step-by-step explanation:

a^2 + a + 1/4=0

a=1

b=1

c=1/4

∆=b²-4.a.c

∆=(1)²-4.(1).(1/4)

∆=1-1

∆=0

a'=a"=-b/2a

a'=a"=-(1)/2.(1)

a'=xla"=-1/2

a^2 + a + 1/4=(a+1/2).(a+1/2)

Ok!
