Question

b) 2(x – 3) + (x – 3) 2 = 0

Answer 1

\(2\left(x-3\right)+\left(x-3\right)2=0\)

\(\Leftrightarrow2x-6+2x-6=0\)

\(\Leftrightarrow4x-12=0\)

\(\Leftrightarrow4x=12\)

\(\Leftrightarrow x=3\)

Answer 2

\(2\left(x-3\right)+\left(x-3\right).2=0\\ \Leftrightarrow4\left(x-3\right)=0\\ \Leftrightarrow x-3=0\\ \Leftrightarrow x=3\)

Answer 3

2(x-3) +\(\dfrac{x-3}{2}\)=0 -->4x-12+x-3=0 --->x=3
