Question

4x-6x во 2 степени=0,      xво 2 степени-144=0

Answer 1

$4x-6x^{2}=0\ -6x^{2}+4x=0\ 6x^{2}-4x=0\ x(6x-4)=0\\ x=0\\ 6x-4=0\ 6x=4 | :6\ x=frac{4}{6}\ x=frac{2}{3}$

 

$x^{2}-144=0\ x^{2}=144\ x=+ / - 12$

Answer 2

1) (4x-6x)^{2}=0

(-2x)^{2}=0

4x^{2}=0

x=0

2) x^{2}-144=0

x^{2}-12^{2}=0
(x-12)*(x+12)=0

х-12=0 или х+12=0
х=12 или х=-12
