Question

Solution of quadratic equation 2x² + 6√3x - 60 = 0 is:​

Answer 1

Answer:

2x^2 + 6_/3x - 60 = 0

2 (x^2 + 3_/3x -30 ) =0

x^2 +3_/3x -30 =0/2

BY SPLITTING THE MIDDLE TERM

x^2 + 3_/3x -30 = 0

x^2 + 5_/3x -2_/3x -30 = 0

x (x+5_/3) - 2_/3 (x+5_/3) =0

(x + 5_/3 ) (x -2_/3 ) =0

x +5_/3 =0 l x -2_/3 =0

x = -5_/3 l x= 2_/3
