Respuesta :
x = 6 ± √30
x² + 2( -6)x + 36 = - 6 + 36
(x - 6)² = 30 ( take the square root of both sides )
x - 6 = ± √30 ( note plus or minus )
add 6 to both sides
x = 6 ± √30 ( exact solutions )
Answer:
[tex]x^2-12x+36= -6+36[/tex]
Step-by-step explanation:
Equation : [tex]x^2-12x = -6[/tex]
General equation : [tex]ax^2+bx+c=0[/tex]
So,we need to add and subtract [tex](\frac{b}{2})^2[/tex] for completing square.
So, next step of completing square :
[tex]x^2-12x+6^2-6^2= -6[/tex]
[tex]x^2-12x+36= -6+36[/tex]
Hence Step 2 shows lamar's next step and the solution to the equation
