FIND THE ERROR Lakeisha and Juanita are determining the number of solutions of 5y 2 - 3y
Chapter 9, Problem 41(choose chapter or problem)
FIND THE ERROR Lakeisha and Juanita are determining the number of solutions of 5y 2 - 3y = 2. Who is correct? Explain your reasoning. Lakeisha 5 y 2 - 3y = 2 b 2 - 4ac = (-3) 2 - 4(5)(2) = -31 Since the discriminant is negative, there are no real solutions. Juanita 5y 2 3y = 2 5y 2 3y 2 = 0 b 2 4ac = (3) 2 4(5)(2) = 49 Since the discriminant is positive, there are two real roots.
