Multiple choice Find the incomplete quadratic equation in $x$, whose solution is $0$. $x^{2} + 4x = 0$ $x^{2} + 4 = 0$ $x^{2} - 4 = 0$ $\dfrac{4}{2}x^{2} = 0$ Reveal answer Fill a bubble to check yourself D Correct answer AI explanation AI 1 An incomplete quadratic equation lacks the linear (x) term, and for its solution to be exactly 0, its constant term must also be 0. Option D, (4/2)x^2 = 0, simplifies to 2x^2 = 0. Solving this yields x^2 = 0, meaning the only solution is x = 0. Thanks Wrong explanation
