The roots of the quadratic equation (3x – 2) (2x + 1) = 0 areA) 2/3, -1/2B) -2/3, -1/2C) -2/3, 1/2D) 2/3, 1/2

Answer»

Correct option is (A) 2/3, -1/2

Given quadratic equation is

\((3x-2)\) \((2x+1)\) = 0

\(\Rightarrow\) 3x - 2 = 0 or 2x+1 = 0

\(\Rightarrow x=\frac23\;or\;x=\frac{-1}2\)

Hence, roots of given quadratic equation are \(\frac23,\frac{-1}2.\)

Correct option is A) 2/3, -1/2
