z^2+3z=-2
What are we solving for?
It says solve the equation.
Not enough information is given.
It states that the answer is a solution set
I can solve for: \[Z, Z^2\]
Okay, that makes sense.
Z = -2, -1 In the set of: \[Z,Z\] as stated.
it simply means that to find the solution to this equation or to find such a value of z that satisfies this equation
so its a second degree equation or quadratic equation means this equation has two solutions or z has two distinct values. factor out z form this equation and solve it i do a little for you z^2+3z = -2 z(z+3) = -2
