Question

2x al cuadrado menos 3x - 2x menor igual que cero

Answer 1

${2x^2-3x-2=0\ \ \ \ \ descomponemos\ el\ -3x}\\\\{2x^2-4x+x-2=0\ \ \ \ agrupamos }\\\\{(2x^2-4x)+(x-2)=0\ \ \ \ sacamos\ factor\ com\'un}\\\\{2x(x-2)+1(x-2)=0}\\\\{(2x+1)(x-2)=0}\\\\\\\\{2x+1=0}\\\\{\boxed{x_1=-\frac{1}{2}}}\\\\\\\\{x-2=0}\\\\{\boxed{x_2=2}}$
