Answer:

x = ± 10

Step-by-step explanation:

Given

f(x) = 8x² - 800

To find the zeros let f(x) = 0, that is

8x² - 800 = 0 ( add 800 to both sides )

8x² = 800 ( divide both sides by 8 )

x² = 100 ( take the square root of both sides )

x = ± [tex]\sqrt{100}[/tex] = ± 10

Thus

smaller solution is x = - 10

larger solution is x = 10
