Question

1)Uprość:

x-2y(3x+5)-4xy

(3x-2)4x+5)+2x(x+3y)

3a-(2a-1)(4b-3)+5

2x(3x+5)(4y-6)-2(x+3y)

-3(5-3a)-(4b-2c)+\frac{1}{4}(a-c)

frac{x-2y}{3}+frac{3x+y}{2}-5(x+3y)

(x+4)^{2}

(2x+5)^{2}

(3x+2y)^{2}

(x-3)^{2}

(3x-4)^{2}

(2y-5x)^{2}

Answer 1

x-6xy-10y-4xy=x-10xy-10y

12x²+15x-8x-10 + 2x²+6xy =14x²+7x-10+6xy

3a-2a+1+20b-15 = 1a-14+20b
