Answer:
x= -3 x = 1/2 x=-2
Step-by-step explanation:
f(x)=(x+3) (2x-1)(x+2)
Set equal to zero
0 =(x+3) (2x-1)(x+2)
Using the zero product property
x+3 =0 2x-1 =0 x+2 =0
x= -3 2x =1 x = -2
x= -3 x = 1/2 x=-2
Convert division to exponent neative
also, n^0=1 so get rid of that nonesense
also we have m^2/m^4 so we are left wiht 1/(m^2) or m^-2
so
=
=
=
=
=
Answer:
Step-by-step explanation:
The given quadratic equation is .
Comparing this equation to: , we have a=2,b=-5.
Where: and
The difference in roots is given by:
Divide both sides by -2
Answer:
only the first option is correct
Step-by-step explanation:
Let the bank balance be b
b is less than $20;
This mean ;
b < $20
So let us select the correct options;
a. This is correct
As we can see, b represents the bank balance which is the variable in the inequality
b. This is incorrect
The inequality symbol is <
c. This is incorrect
The inequality symbol needed is not 20
