Expert Answer
2 x2 - 5x + 3 = 0
Above quadratic equation is solved by factoraisation method.
Middle term -5x can be written as a sum of -3x and -2x so that product equals 6 which is the
product of coefficient of x2 and constant term ( 2 × 3 = 6 )
2x2 - 3x - 2x +3 = 0
x( 2x-3) - (2x-3) = 0
( x -1 ) ( 2x - 3 ) = 0
hence we get the roots as 1 and (3/2)
