Question

F(x)=8x^2 -800 Enter the solutions from least to greatest.

Answer 1

x = -10, 10

Explanation:

Step 1: Write out function

f(x) = 8x² - 800

Step 2: Set equal to 0

0 = 8x² - 800

Step 3: Add 800 on both sides

800 = 8x²

Step 4: Divide both sides by 8

x² = 100

Step 5: Take square root on both sides

x = ±10

Step 6: Arrange

-10 < 10

So x = -10, 10
