Question

Solve the equation by factoring.
6x(x − 1) = 40 − 5x
x =____ (smaller value)
x =____ (larger value)

Answer 1

x=-5/2,8/3

Answer 2

6x*2 -6x=40-5x
6x*2 -x-40 = 0
1 +/- radical (1+960) 1+/- radical 961 1+/- 31,9
x_1,_2= ----------------- = -------------- = ---------
12 12 12

x_1=-30,9/12 = -15,45/6=-7,725/3
x_2=32,9/12 =16,45/6 =8,225/3
