Which equation is equivalent to the given equation? 0= -x² + x + 12
x² + x + 12 = 0
x² - x + 12 = 0
x² + x - 12 = 0
x² - x - 12 = 0

x² - x - 12 = 0

Step-by-step explanation:

0 = -x² + x + 12

→ Add x² to both sides

x² = x + 12

→ Minus x from both sides

x² - x = 12

→ Minus 12 from both sides

x² - x - 12 = 0
