Question

Find the roots of the following quadratic equation by factorisation: x - 3/x = 2

Answer 1

Answer:

x = 3 or x = -1

Step-by-step explanation:

Given Quadratic equation ,

x - 3/x = 2

=> ( x² - 3 )/x = 2

=> x² - 3 = 2x

=> x² - 2x - 3 = 0

Splitting the middle term , we get

=> x² -3x + 1x - 3 = 0

=> x( x - 3 ) + 1( x - 3 ) = 0

=> ( x - 3 )( x + 1 ) = 0

Therefore ,

x - 3 = 0 or x + 1 = 0

x = 3 or x = -1
