1. The problem is to apply the zero product property to solve an equation of the form $ab=0$. 2. The zero product property states that if the product of two factors is zero, then at least one of the factors must be zero. Mathematically, if $ab=0$, then either $a=0$ or $b=0$. 3. To use this property, first factor the equation completely if it is not already factored. 4. Then set each factor equal to zero and solve for the variable. 5. For example, if the equation is $(x-3)(x+5)=0$, then by the zero product property: $$x-3=0 \quad \text{or} \quad x+5=0$$ 6. Solving these gives: $$x=3 \quad \text{or} \quad x=-5$$ 7. These are the solutions to the equation using the zero product property.
