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.
Desmonds height let’s say x = y + 3
The discriminant of this equation is 49. The solutions for this equation are x=2 and x=-
I hope that helps.
Answer:
{x,y} = {19/12,5/6}
Step-by-step explanation:
A) Divide total miles by total time:
