Factor 60x2 – 155x + 100 completely

hello :

60x² – 155x + 100 = 5 ( 12 x² - 31 x + 20 )

delta of ( 12x² - 31 x + 20 ) is b² - 4ac   when : a = 12    b = -31   c = 20

delta = ( - 31 )² - 4(12)(20) = 961 - 960 = 1

x1 = (31-1)/24 = 30/24 = 5/4

x2 =  (31+1)/24 = 32/24 = 4/3

Factor 60x2 – 155x + 100 = 5 (12(x -5/4)(x- 4/3)) = 60 (x -5/4)(x- 4/3)

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
