Answer = 0.6
a = 6; b = (– 6); c = 6
x1;2 = – b ± √ b² – 4·a·c
2·a
x1;2 = – (– 6) ± √ (– 6)² – 4·6·6
2·6
x1;2 = 6 ± √ (– 6)² – 4·6·6
12
x1;2 = 6 ± √ 36 – 144
12
Step-by-step explanation:
6·x² – 6·x + 6 = 0 ... 1.25·x² – 7·x + 1 = 0 · 5·x² + 4·x – 3 = 0 · – x² + 8·x – 33 = 0 · – x² + 8·x + 33 = 0 · 2·x² – 37·x + 168 = 0 · – 60·x² + 64·x – 16 ...
