Question

Are x=0,x=-1 the solution of the equations x2+x+1=0

Answer 1

Answer:

No

Step-by-step explanation:

1) p(x)= x2+x+1

p(0)=0×2+0+1

p(0)= 0+0+1 = 1

1≠0

∴x=0 is not the solution of the equation x2+x+1=0

2) p(-1) = -1 ×2 + (-1) + 1

p(-1) = -2 -1 +1

p(-1) = -2

-2≠0

∴x=-1  is not the solution of the equation x2+x+1=0
