Find the solution to the following equation by transforming it into a perfect square trinomial.
x2 – 12x = 13
{46, 55}
{–1, 13}
{–15, 27}
{–21, 33}

X² -12x  = 13                       way to obtain 36   >       (-12/2)²  =  36    
x²  -12x + 36 =13 +36      since we add 36 to the left,we must also add 36 to the right
(x-6)²  =  49
x-6  =    7
x  =    7 + 6 =  13    or      -7 + 6  = -1
x =  -1    or    13

The linear equation is: y=ax+b
