POR FAVOR ME AJUDEMM

Answer 1

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

b) 7(x-2y) = 7x-14y

c) 2x(x+y) = 2x²+2xy

d) 4x(a+b) = 4ax+4bx

e 2x(x²-2x+5) = 2x³-4x²+10x

f) (x+5)(x+2) = x²+2x+5x+10 = x²+7x+10

g) (3x+2)(2x+1) = 6x²+3x+4x+2 = 6x²+7x+2

h) (x+7)(x-4) = x²-4x+7x-28 = x²+3x-28

i) (3x+4)(2x-1) = 6x²-3x+8x-4 = 6x²+5x-4

j) (x-4y)(x-y) = x²-xy-4xy-4y² = x²-5xy-4y²
