Question

Nikolas and Angela were trying to solve the equation:

3x^2+10x=0
Nikolas said, “I can complete the square. Half of 10 is 5, and 5 squared is 25. So I'll add 25 to both sides, factor, and solve.”
Angela said, “I'll factor the left-hand side of the equation as x(3x+10), and solve using the zero product property."
Whose solution strategy will work?

Answer 2

• Answer:

zero product property (Angela)

• Explanation:

Hi there !

(Angela)

3x² + 10x = 0

x(3x + 10) = 0

x = 0 => x₁ = 0

3x + 10 = 0 => 3x = - 10 => x₂ = - 10/3 = - 3 1/3

Good luck !
