Answer 1

$1.\\1. 10a + 15b =5(2a+3b)\\2. 2ab - 5b = b(2a-5)\\3. x^{5} -x^{4} =x^{4} (x-1)\\4. 2m^{6}+8m^{3}=2m^{3} (m^{3} +4)\\5. 3xy^{2} +6y= 3y(xy+2)\\6. b(3-x) -4(3-x)=36b-24bx+4x^{2} b\\7. 5(a-b)+x(b-a)=5a-5b+xb-xa\\8. (x-4)(2x-1)+(4-x)(x+4)=x^{2} -9x+20\\2.\\1) x^{2} -6x=0\\x(x-6)=0\\x=0;x=6\\\\2. (4-x)(4x-8)-(4x-8)(6-x)=0\\(4x-8)(4-x-6+x)=0\\(4x-8)*-2=0\\-8x+16=0\\-8x=-16\\x=2$
