Answer 2

$\\ \rightarrowtail \sf{f(x)=2x^2−1;g(x)=1−3x}$

$\\ \rightarrowtail \sf2x^2−1=1−3x$

$\\ \rightarrowtail \sf2x^2+3x−2=0$

$\\ \rightarrowtail \sf2x^2+3x−2=0$

$\\ \rightarrowtail \sf2x^2+4x−x−2=0$

$\\ \rightarrowtail \sf2x^2(x+2)−1(x+2)=0$

$\\ \rightarrowtail \sf(2x^2−1)(x+2)=0$

$\\ \rightarrowtail \sf \: x = \frac{1}{ \sqrt{2} } .. \frac{ - 1}{ \sqrt{2}.. } - 2$
