Answer:

x=2 and -2

Step-by-step explanation:

f(x)=2x^2-8

set the function equal to zero to solve for x

2x^2-8=0

add 8 to both sides and divide by 2

x^2=4

take the square root of both sides to get x isolated

√(x^2)=√4

x= ±2

Solve the second equation.<br>2x - y = 8<br>First, solve for (-y).<br>--y =<br>​
kicyunya [14]

Answer:

-y=-2x+8\\y=2x-8

Step-by-step explanation:

To solve, first subtract 2x from both sides.

2x-y=8\\-y=-2x+8

You appear to want the solution for -y, so I've included it. Given that you also want the solution for y, divide both sides by -1.

-y=-2x+8\\y=2x-8
