Question

Solve the following quadratic equation for x 43x2+5x-23=0​

Answer 1

4√3 x2 + 5x -2√3 = 0

 

By factorisation

 

4√3 x2 + 8x -3x -2√3 = 0

 

4x(√3 x + 2 ) -√3 (√3 x + 2 ) = 0

 

(√3 x + 2 ) (4x - √3 ) = 0

 

Hence x = √3/4  or x = -2/√3

---------------------------------------

By quadratic eqn. formula
