Solve the question by completing the sqaure x² + 4x = 0?

Mathematics
1 answer:
n200080 [17]2 years ago
3 0

Answer:

x = 0 or -4

Step-by-step explanation:

x² + 4x = 0

To complete the square, take half of the middle coefficient, square it, then add to both sides.

(4/2)² = 2² = 4

x² + 4x + 4 = 4

(x + 2)² = 4

x + 2 = ±2

x = -2 ± 2

x = 0 or -4

Josefina pain rent for 5 months. She paid a total of $2045. how much did she pay per month?
djverab [1.8K]

Answer:

$409 per month

Step-by-step explanation:

If josefina paid $2045 over a time period of 5 months, then we have to divide how much she paid ($2045) by 5 to find out how much she paid for rent in 1 month.

We can use the equation: 2045 ÷ 5

When we solve that equation, we get 409 which means that josefina paid $409 per month for rent.

(sorry if this is confusing but I hope it helped)
