Answer:
The 2nd, 3rd, and 8th choice
Step-by-step explanation:
The correct answers are: 1/2, 2 and -2.
To get this, factor f(x)
f(x)=2x^3-x^2-8x+4
f(x)= (2x^3-x^2) - (8x -4)
f(x)= (2x-1)(x^2) + (2x-1)(-4)
f(x)= (2x-1)(x^2-4)
f(x)= (2x-1)(x-2)(x+2)
2x-1=0
2x=1
x=1/2
x-2=0
x=2
x+2=0
x=-2
3abc / abc
= 3 ( abc ) / abc
= 3
because the real numbers did not have zero. the real number are starting from positive 1 to positive infinity number.
If we suppose a = 1, b = 2, c = 3
abc / abc = 1.
I hope that i helped you :)
X+x^2=2
x^2+x-2=0
(x+2)(x-1)=0
So x=-2, 1
