Question

solve the equation using the quadratic formula: x^2+4=4x

Answer 1

\[
x^2+4 =4 x\\
x^2-4 x + 4 =0\\
(x-2)^2=0\\
x=2
\]

Answer 2

Do it with the quadratic formula and confirm the answer above.

Answer 3

I need help with setting up the quadratic formula i can't get it set up right.

Answer 4

\[

x^2-4 x + 4=0\\
a=1; b=-4; c=4\\
\Delta = b^2-4 a c= 16- 4(1)(4)=0\\
x=\frac { -b\pm \sqrt \Delta}{2 a}=\frac { 4\pm 0}{2}=2
\]
