1) 5a-(a+1)(4a+1)=5a-4a²-a-4a-1=-(4a²+1)
2) a(2a-1)+(a+3)(a-5)=2a²-a+a²-5a+3a-15=3a²-3a-15=3(a²-a-5)
3) (x-3)(x+7)-x(x+4)=x²+7x-3x-21-x²-4x=-21
4) (p+3c)c-(3c+p)(c-p)=pc+3c²-3c²+3pc-pc+p²=p²+3pc=p(p+3c)

1) (5x+1)(2x-3)=(10x-3)(x+1)
10x²-15x+2x-3=10x²+10x-3x-3
-13x=7x
-20x=0
x=0
2) (7x-1)(5+x)=(3+7x)(x+3)
35x+7x²-5-x=3x+7x²+9+21x
10x=14
x=1.4
3)
1) xy(x+y)-(x²+y²)(2x-y)=x²y+xy²-2x³+x²y-2xy²+y³=2x²y-xy²-2x³+y³=2x²(y-x)+y²(y-x)=(y-x)(2x²+y²)
2) (8a+3b)(3a-8b)-(3a+8b)(8a-3b)=24a²-64ab+9ab-24b²-24a²+9ab-64ab+24b²=-110ab
3) (p³-3k)(p²+3k)-(p²-3k)(p³+3k)=p⁵+3p³k-3p²k-9k²-p⁵-3p²k+3p³k+9k²=6p³k-6p²k=6p²k(p-1)
