Solve for x over the real numbers:
x^2 - 4 x - 5 = 0
The left hand side factors into a product with two terms:
(x - 5) (x + 1) = 0
Split into two equations:
x - 5 = 0 or x + 1 = 0
Add 5 to both sides:
x = 5 or x + 1 = 0
Subtract 1 from both sides:
Answer: x = 5 or x = -1

Answer:
x = 1/2
y = 24
Step-by-step explanation:
y = 12 / x
y = 6 / x²
12 / x = 6 / x²
x² / x = 6 / 12
x = 1 / 2
y = 12 / x
y = 12 / (1/2)
y = 24
Answer: 20 because u do subtract the add the divde if its say why
