5*x^2 - 12*x + 4)/ (6 - 15*x)

Question

5*x^2 - 12*x + 4)/ (6 - 15*x)

Answer 1

5*x^2 - 12*x + 4= 

(6 - 15*x)

  5*x^2 - 12*x + 4=0

D=144-4*5*4=144-80=64

x1=(12-8)/10=20/10=2

x2=(12-8)/10=4/10=2/5

  5*x^2 - 12*x + 4=5(x-2)(x-2/5) 

 

5*x^2 - 12*x + 4=  5(x-2)(x-2/5) 

 (6 - 15*x)               3(2-5x)
