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

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
