Question

Uprosc wyrazenie algebraiczne :

a) x(x-5)-(x-y)(x+3y)=

b) -(7a-c)(a+c)-2a(a-c)=

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

d) -( (x-y)(x-2y)-5x^2)+2x^2=

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

Prosze pomozcie mi jest mi to potrzebne na teraz .

Daje naj :)

Z gory dzieki :)

Answer 1

a) x^{2}-5x-x+y+x+3y = x^{2} - x + 4y

b) -7a+c+a+c-2a^{2} + 2ac = -6a + 2c + 2ac + 2a^{2}

c) -x+5y+2x-y+3x^{2}-y=4x+3y+3x^{2}

d)-x+y-x+2y+5x^{2} + 2x^{2} = -2x+7x^{2}+3y+

e) xy-5y^{2}-2x+y-x+3y= -5y^{2}-3x+xy+4y
