Consider the quadratic function: f (x) = 5x2 + 20x + 20. What are the zeros of the function using completing the square?

Step-by-step explanation:

step 1. f(x) = 5x^2 + 20x + 20

step 2. f(x) = 5(x^2 + 4x + 4)

step 3. f(x) = 5(x + 2)^2

step 4. 0 = 5(x + 2)^2

step 5. zeros: -2

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400
