25x²+17=42x
25x²-42x+17=0
D=(-(-42))²-4×25×17=1764-1700=64
x1=(-(-42)-√64)/2×25=(42-8)/50=34/50=17/25
x2=(-(-42)+√64)/2×25=(42+8)/50=50/50=1
Проверка:
25х²+17=42х
25×(17/25)²+17=42×17/25
(17²×25/25×25)+17=(714/25)
(289/25)+17=(714/25)
((289+17×25)/25)=(714/25)
((289+426)/25)=(714/25)
(714/25)=(714/25)-истина.
25х²+17=42х
25×1²+17=42×1
25+17=42
42=42-истина.
