Question

ajuda e urgente por favor​

Answer 1

a) 2x²-10x = 0

2x(x-5) = 0

2x = 0

x = 0/2

x = 0

x-5 = 0

x = 5

S = {0,5}

b) x²+3x = 0

x(x+3) = 0

x = 0

x+3 = 0

x = -3

S = {-3,0}

c) 6x-12x² = 0

6x(1-2x) = 0

6x = 0

x = 0/6

x = 0

1-2x = 0

-2x = -1

x = 1/2

S = {0,1/2}

❤️ Bom domingo ❤️
