Question

For what values of m square x square + 2( m+1) +4= 0 will have exactly one zero

Answer 1

Answer:

-3

Step-by-step explanation:

For one zero

b²-4ac = 0 if quadratic equation is ax²+bx+c=0

here in ur asked equation,,

a=1

b=0 as there is no coefficient of x

c= 2(m+1) +4=2m +2+4 = 2m +6

Substitution in  b²-4ac = 0

0²-4(1) (2m+6)=0

0=4(2m+6)

2m+6=0

m=-6/2=-3
