Question

6x²-(2x-3)(3x+2)-1=0

Answer 1

\(6x^2-\left(2x-3\right)\left(3x+2\right)-1=0\)

\(\Rightarrow6x^2-6x^2+5x+6-1=0\)

\(\Rightarrow5x=-5\Rightarrow x=-1\)

Answer 2

\(\Rightarrow6x^2-\left(6x^2-5x-6\right)-1=0\\ \Rightarrow5x+5=0\\ \Rightarrow x=-1\)

Answer 3

\(6x^2-\left(2x-3\right)\left(3x+2\right)-1=0\)

\(\Leftrightarrow6x^2-6x^2-4x+9x+6-1=0\)

\(\Leftrightarrow x=-1\)
