Question

\(\left(x-2\right)^2+4\left(4-x\right)\)

Answer 1

=x^2-4x+4+16-4x

=x^2-8x+20

Answer 2

\(=x^2-4x+4+16-4x\)

\(=x^2-4x-4x+4+16\)

\(=x^2-8x+20\)

Answer 3

(x - 2)² + 4(4 - x)

= x² - 4x + 4 + 16 - 4x

= x² - 8x + 20

Answer 4

\(\left(x-2\right)^2+4\left(4-x\right)\)

\(=x^2-4x+4+16-4x\)
\(=x^2-8x+20\)
\(=x^2-8x+4^2+4\)
\(=\left(x-4\right)^2+4\)
