Question

На множители выражение: 1. 36x^2-24x^42. 4ax-6ay^2+6x-9y^23.3(x-3)^2+2x(3-x)=0

Answer 1

1. $36x^{2} -24 x^{4} =6 x^{2} (6-4 x^{2} )$
2. $4ax-6a y^{2} +6x-9 y^{2} =2a(2x-3 y^{2} )+3(2x-3 y^{2} )=$$(2a+3)(2x-3 y^{2})$
3. $3(x-3) ^{2} +2x(3-x)=3(3-x) ^{2} +2x(3-x)=$$3(3-x) (3-x) +2x(3-x)=(3-x)(9-3x+2x)=(3-x)(9-x)$
