Answer:
Step-by-step explanation:
3x²+11x-4
when splitting the middle term
it becomes
3x²+12x-1x-4
=3x(x+4)-1(x+4)
(3x-1)(x+4)
either 3x-1=0 then x=1/3
or x+4=0 then x= -4
m=1/3
n=-4
therefore
value of m divided n plus n dividedm=1.25
hope this helps plzz mar me brainliest
x^3 - 8x² - x + 8 =0
x^3 - 8x² - (x - 8 )=0
x²(x-8) - (x-8) = 0
(x-8)(x² -1) =0
x-8 = 0 or x² - 1 = 0
x-8=0 or (x-1)(x+1)=0
x=8 x=1 or x=-1
postive 12
16-4=12
