Answer:
x = 12.63 or x= -0.63
Step-by-step explanation:
From my understanding the question is x² - 12x = 8
This will be solved through a quadratic equation formula.
Step 1: Form a quadratic equation
x² - 12x = 8
x² - 12x - 8 = 0
Step 2: Apply the quadratic formula
a = 1, b = -12, c = -8
x = -b±√b²-4ac
2a
x = -(-12)±√(-12)²-4(1)(-8)
2(1)
Step 3: Find the value of x
x = 12±4√(11
2
x = 12+4√(11) or x = 12-4√(11)
2 2
x = 12.63 or x= -0.63
