Q. (3x−2)(x+3)(2x+1)=0How many distinct roots does the given equation have?Choose 1 answer:(A) Zero(B) One(c) Two(D) Three
Equation factors: The given equation is a product of three factors set equal to zero: (3x−2)(x+3)(2x+1)=0. To find the roots, we need to set each factor equal to zero and solve for x.
Solving first factor: First factor: 3x−2=0To solve for x, we add 2 to both sides of the equation:3x−2+2=0+23x=2Now, we divide both sides by 3 to isolate x:33x=32x=32We have found the first root, x=32.
Solving second factor: Second factor: x+3=0To solve for x, we subtract 3 from both sides of the equation:x+3−3=0−3x=−3We have found the second root, x=−3.
Solving third factor: Third factor: 2x+1=0To solve for x, we subtract 1 from both sides of the equation:2x+1−1=0−12x=−1Now, we divide both sides by 2 to isolate x:22x=2−1x=−21We have found the third root, x=−21.
Number of distinct roots: We have found three distinct roots for the equation: x=32, x=−3, and x=−21. Therefore, the correct answer to the question of how many distinct roots the equation has is 3.
