Question

Solve the equation: x2 - 12x = -36

Answer 1

\[x^2-12x+36\]
\(a=1,b=-12,c=36\)
then use the quadratic formula
\[x=\frac{-(b)\pm\sqrt{(b)^{2}-4(a)(c)}}{2a} \]

Answer 2

\(x^2-12x+36=0\)*

Answer 3

it's factorable -6,-6 =P

Answer 4

Why can;t we just factor this by the way?? :o

\(x^2 - 6x - 6x +36\)
\(=x(x-6)-6(x-6)\)
\(=(x-6)^2\)

Answer 5

yeah lol.
\(x^2-12x=-36\) => \(x^2-12x+36\)
\(a+b= -6+-6\)
\(a*b=6*6\)
you can justuse the quadratic formula anyway; its faster.
