Question

por favor =( me ajudem...​

Answer 1

a) 5a(2a+2) = 10a²+10a

b) 2y²(y²+5y-2) = 2y⁴+10y³-4y²

c) 3x(x²-x+1) = 3x³-3x²+3x

d) m³(3m²+m) = 3m⁵+m⁴

e) (x+y)(x-y) = x²-xy+xy-y² = x²-y²

f) (2x+1)(4x-2) = 8x²-4x+4x-2 = 8x²-2

g) (2x²+x)(x²-3) = 2x⁴-6x²+x³-3x

h) (-3y³+2y)(y²+1) = -3y⁵-3y³+2y³+2y = -3y⁵-y³+2y

❤️ Prontinho ❤️
