Question

Zastosuj wzory skróconego mnożenia:

Answer 1

a)(4x+2y)²=16x²+16xy+4y²

b)(3xy-2x)²=9x²y²-12x²y+4x²

c)(12xz-4xy)(12xz+4xy)=144x²z²-16x²y²

d)(5x²y²-6xy)²=25x⁴y⁴-60x³y³+36x²y²

Answer 2

a)=16x^(2)+16xy+4y^(2)

b)=9x^(2)y^(2)-6x^(2)y+4x^(2)

c)=144x^(2)z^(2)-16x^(2)y^(2)

d)=25x^(4)y^(4)-60x^(3)y^(3)+36x^(2)y^(2)
