Question

(2x - 3)² + 12x = 9​

Answer 1

$\Rightarrow \ \ \ (2x \ - \ 3)^{2} \ + \ 12x \ \ = \ \ 9 \\\\ \Rightarrow \ \ \ (2x \ - \ 3) (2x \ - \ 3) \ \ + \ 12x \ \ = \ \ 9 \\\\ \Rightarrow \ \ 2x^{2} \ - \ 12x \ + \ 9 \ + \ 12x \ \ = \ \ 9 \\\\ \Rightarrow \ \ \ 2x^{2} \ + \ 9 \ \ = \ \ 9 \\\\ \Rightarrow \ \ \ 2x^{2} \ \ = \ \ 9 \ - \ 9 \\\\ \Rightarrow \ \ \ 2x^{2} \ \ = \ \ 0 \\\\ \Rightarrow \ \ \ \boxed{ \ x \ \ = \ \ 0 \ }$
