Example 5 Find the roots of the quadratic equation 3x2 โ 2 โ6 ๐ฅ + 2 = 0 . 3x2 โ 2 โ6 ๐ฅ+2=0 We will factorize using splitting the middle term method 3x2 โ โ6 ๐ฅโโ6 ๐ฅ+2=0 3x2 โ โ(2ร3) ๐ฅโโ(2ร3) ๐ฅ+2=0 3x2 โ (โ2)(โ3)๐ฅโ(โ2)(โ3)๐ฅ+2=0 โ3 ๐ฅ(โ3 ๐ฅโโ2 )โโ2 (โ3 ๐ฅโโ2 )=0 (โ3 ๐ฅ โโ2) (โ3 ๐ฅโโ2)=0 Hence x =โ(2/3) & x =โ(2/3) are roots of the equation
