Question

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

Answer 1

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
