Respuesta:
25x²+110x+121 = 0
25x²+55x+55x+121 = 0
5x(5x+11)+11(5x+11) = 0
(5x+11)(5x+11) = 0
(5x+11)² = 0
√((5x+11)²) = ±√(0)
5x+11 = 0
5x+11-11 = 0-11
5x = - 11
5x×(1/5) = (1/5)×(-11)
x = (-11/5)
Verificación :
25(-11/5)²+110(-11/5)+121 = 0
25(121/25)-22(11)+121 = 0
121-242+121 = 0
- 121 + 121 = 0
0 = 0
R// El valor de " x " es - 11/5 .
