Answer 1

Răspuns:

1) = (√2x-1)² = 0

√2x-1 = 0

√2x = 1

x = 1/√2

x = √2/2 → cine

2) = 2x²-2x-1 = 0

x(2x+1)-(2x+1) = 0

(2x+1)(x-1) = 0

2x+1 = 0

x-1 = 0

x1 = -1/2

x2 = 1 → seamana

3) = x²+2x-5x-10 = 0

x(x+2)-5(x+2) = 0

(x+2)(x-5) = 0

x+2 = 0

x-5 = 0

x1 = -2

x2 = 5 → vânt

4) = 16x²+6x-1 = 0

16x²+8x-2x-1 = 0

8x•(2x+1)-(2x+1) = 0

(2x+1)(8x-1) = 0

2x+1 = 0

8x-1 = 0

x1 = -1/2

x2 = 1/8 → culege

5) = x = 0

x+√15 = 0

x1 = -√15

x2 = 0 → furtuna

Rezultatul obtinut:

Cine seamana vant culege furtuna.
