Q. (2x−1)(x−5)(x+2)=0What is a positive root of the given equation?□
Given Equation Roots: We are given the equation 2x-1)(x-5)(x+2)=0\. To find the roots of the equation, we need to set each factor equal to zero and solve for \$x.
Factor 1: First, let's set the first factor equal to zero: 2x−1=0. Solving for x gives us x=21.
Factor 2: Next, we set the second factor equal to zero: x−5=0.Solving for x gives us x=5.
Factor 3: Finally, we set the third factor equal to zero: x+2=0. Solving for x gives us x=−2.
Positive Roots: Now we have three roots: x=21, x=5, and x=−2. The question asks for the positive root.
Final Answer: Looking at the roots we found, the positive roots are x=21 and x=5. Since we are asked for a single positive root, we will provide both as the answer.
