Full solution

Q. (2x1)(x5)(x+2)=0 (2 x-1)(x-5)(x+2)=0 \newlineWhat is a positive root of the given equation?\newline \square
  1. 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.
  2. Factor 11: First, let's set the first factor equal to zero: 2x1=02x - 1 = 0. Solving for xx gives us x=12x = \frac{1}{2}.
  3. Factor 22: Next, we set the second factor equal to zero: x5=0x - 5 = 0.\newlineSolving for xx gives us x=5x = 5.
  4. Factor 33: Finally, we set the third factor equal to zero: x+2=0x + 2 = 0. Solving for xx gives us x=2x = -2.
  5. Positive Roots: Now we have three roots: x=12x = \frac{1}{2}, x=5x = 5, and x=2x = -2. The question asks for the positive root.
  6. Final Answer: Looking at the roots we found, the positive roots are x=12x = \frac{1}{2} and x=5x = 5. Since we are asked for a single positive root, we will provide both as the answer.
