Question

one root of the equation x^2+x+4=0 is common with equation x+2=0 the statement is true or false or can't say​

Answer 1

Hey

x^2+x+4=0

Solution of the equation x+2=0

=>x = -2

To assess whether x=-2 is a zero of first equation,

=x^2+x+4

=(2)^2+2+4=4+4+2=10

LHS≠RHS

As,10≠0

The statement is false
