Given : Nando has 4 goldfish. Jill has 3 goldfish. Cooper has 2 times as many goldfish as Nando and Jill combined.
i.e. Number of goldfish Cooper has =
To write the equation that compares the number of goldfish Cooper has with the number of goldfish that Nando and Jill have , we denote the number of goldfish Cooper has as "c", we get
The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0. When the product of factors equals zero, one or more of the factors must also equal zero. Once the polynomial is factored, set each factor equal to zero and solve them separately.
