PLZ HELP!! Which real numbers are zeroes of the function?

astra-53 [7]

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

X+3y=3<br> 2x-4y=6<br><br> solve the equations

Gelneren [198K]

Subtract the second equation from double the first equation:

2x+6y-2x-(-4y)=0

10y=0

Therefore, y=0. Substituting this into the first equation, we see that:

x+3(0)=3

x=3

Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).
