Answer 1

Respuesta:

b= 3[2ab(2)-5a(2)b+4]

d= -(11/9x(2)+1/6xy(2))

Explicaciónhttps:

$b= ab^{2} - 3a^{2} b +5ab^{2} -12a^{2}b+12\\ b= 6ab^{2} -15a^{2} b+12\\b=3[2ab^{2} -5a^{2} b +4]\\\\d=0.7x^{2} -1/3xy^{2} +x^{2} -3x^{2} +1/6xy^{2} \\d= 7/9x^{2} -1/3xy^{2} +x^{2} -3x^{2} +1/6xy^{2} \\d= -11/9x^{2} -1/6xy^{2} \\ d=-(11/9x^{2} +1/6xy^{2} )$
