120 a2+118 a - 10 = 0
Answers
Answer:
120a² + 118a - 10 = 0
a = ( -B ± √B² - 4AC )/2A
= ( -118 ± √118² + 4x120x10 ) / 2x120
= ( -118 ± √13924 + 48000) / 240
= ( -118 ± √61924 ) / 240
= ( -118 ± 248.8453 ) / 240
CASE 1 : CASE 2:
(-118 + 248.8453) / 240 (-118 -248.8453) / 240
130.8453 / 240 - 366.8453 / 240
0.54518875 -1.52852208333
a=0.545 a= -1.529 (ANSWER.)
Answer:
120a²+118a-10=0
60a²+59a-5=0
-59±√(59²-4×60×-5)÷2×60
-59±(√4281)÷120
case:1 =(-59-√4281)÷120 case:2 =(-59+√4281)÷120
= -1.03 = 0.0535
