Question

Va rog urgenttt!! Am nevoie cat mai rapid!

Answer 1

1)

2(a+b)

3(x-y)

3(3x+y)

5(2a-3b)

x^2(x-1)

x(2x^2 -3)

xy(1+x^2)

3x^2(3y-4)

xy(4yz-3)

radical(3)abc(3a+2c)

5radical(3)ab(4a^2b-radical(2))

2)

3(a+b-c)

x(x^3+2x^2-1)

xy(1-2x-y)

3(y^2-2y^3+3)

a^2(ab^2-2-b^2)

x(9x^3-12x+8)

6a^2b^2(4a-2b-1)

xy(2-3x-6y)

x(x^3-x^2+2x-3)

xy(1+x+y-xy)

a(a^4-3a^3+2a-1)

xyz(x^2-2y+3xy^2z^3-1)

m)radical(2)xy(radical(6)xy-radical(3)y+

radical(3)x+2-radical(6)x^2y^2)

3)

a)(x+1)(y+z)

b)(y-1)(x-2)

c)(2y+1)(x^2-3)

d)(x+3)(x+2-x)=2(x+3)

e)(2x-1)(2x-1+3)=(2x-1)(2x+2)=

=2(2x-1)(x+1)

f)(x+5)(x+5-x)=5(x+5)

g)(y-1)(y-1+x+2)=(y-1)(x+y+1)

h)(x+3)(x+1+x+3+x+2)=(x+3)(3x+6)=

=3(x+3)(x+1)

i)(x+y)(x-y-x^2-y^2-2x+y)=(x+y)(-x-x^2-y^2)

j)(x+1)[x+1+2-(x+1)^2+x-5)=

=(x+1)(2x-2-x^2+2x-1)=(x+1)(4x-x^2-3)

k)(x-y)(x+y+x-y-3x+2y+x+3y)=(x-y)5y

l)(x-3y)(4+x+1-y+1+x-3y)=(x-3y)(2x-4y+6)
