Multiple choice The root of the polynomial equation $3x-1=0$ is. $x=-\dfrac{1}{3}$ $x=\dfrac{1}{3}$ $x=1$ $x=3$ Reveal answer Fill a bubble to check yourself B Correct answer Explanation 3x - 1 = 0 implies 3x = 1, so x = 1/3. AI explanation AI 1 To find the root of the linear equation 3x - 1 = 0, isolate x by adding 1 to both sides to get 3x = 1. Dividing both sides by 3 then gives x = 1/3. Thanks Wrong explanation
