Question

Desarrolle (5w+x)^2 Desarrolle (10x+w)^2 Desarrolle (7x-8)^2 Desarrolle (9z-10)^2 Desarrolle (y+9)^3

Answer 1

Respuesta:

Explicación paso a paso:

(5w+x)²=(5w)²+2(5w)(x)+(x)²=25w²+10xw+x²

(10x+w)²=(10x)²+2(10x)(w)+(w)²=100x²+20xw+w²

(7x-8)²=(7x)²-2(7x)(8)+(8)²=49x²-112x+64

(9z-10)²=(9z)²-2(9z)(10)+(10)²=81z²-180z+100

(y+9)³=(y)³+3(y)²(9)+3(y)(9)²+(9)³=y³+27y²+243y+729
