What is 6a squared - 12a+36

Sagot :

Edmonton
6a²-12a+36= 6a²-12a=-36  
Put the normal number on the other side to have the variables on one side, and the normal number on the other.
Then group:
                = 36a-12a= -36
                = 24a=-36
Then isolate a:
                = a=-36/24
Then simplify:
                =a = - 3/2

Hope this helps!

6a² - 12a + 36 = 0
a = -(-12) +/- √((-12)² - 4(6)(36))
                        2(6)
a = 12 +/- √(144 - 864)
                    12
a = 12 +/- -√720
            12
a = 12 +/- -√(9 × 16 × 5)
                   12
a = 12 +/- -√9 -√16 -√5
                   12
a = 12 +/- (-3)(-4) -√5
                 12
a = 12 +/- 12-√5
              12
a = 12 +/- 12(-2.236067978)
                      12
a = 12 +/- (-26.83281573)
                     12
a = 12 + (-26.83281573)            a = 12 - (26.83281573)
                    12                                              12
a = 12 - 26.83281573                a = 12 + 26.83281573
                   12                                              12
a = -14.83281573                      a = 38.832815723
