What is the solution of the equation x2 - 12x = 8?

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
