Question

1,44x^2-10,98=0 ayuda porfavor

Answer 1

Respuesta:

1,44x²-10,98 = 0 ; 1,44 = 144/100 = (144÷4)/(100÷4) = 36/25 ====== > 1,44 = (36/25)

(36/25)x²-10,98 = 0 ; 10,98 = 1098/100 = (1098÷2)/(100÷2) = 549/50 ===== > 10,99 = 549/50

(36/25)x²-(549/50) = 0

50(36/25)x²-50(549/50) = 0(50)

2(36)x²-549 = 0

72x²-549 = 0

(72x²-549)/3 = 0/3

(72/3)x²-(549/3) = 0

24x²-183 = 0

(2√(6)x-√(183))(2√(6)x+√(183)) = 0

x1 = (√(183)/2√(6)) y x2 = ( -√(183)/2√(6))
