Answer:
Given: x2−5x−10=0
Given: x2−5x−10=0Here, a=1,b=−5 and c=−10
Given: x2−5x−10=0Here, a=1,b=−5 and c=−10∴ D=b2−4ac
Given: x2−5x−10=0Here, a=1,b=−5 and c=−10∴ D=b2−4ac=(−5)2−4×1×−10=65
Given: x2−5x−10=0Here, a=1,b=−5 and c=−10∴ D=b2−4ac=(−5)2−4×1×−10=65x=2a−b±D
Given: x2−5x−10=0Here, a=1,b=−5 and c=−10∴ D=b2−4ac=(−5)2−4×1×−10=65x=2a−b±D=2×15±65=25±8.06
Given: x2−5x−10=0Here, a=1,b=−5 and c=−10∴ D=b2−4ac=(−5)2−4×1×−10=65x=2a−b±D=2×15±65=25±8.06=25+8.06,25−8.06
Given: x2−5x−10=0Here, a=1,b=−5 and c=−10∴ D=b2−4ac=(−5)2−4×1×−10=65x=2a−b±D=2×15±65=25±8.06=25+8.06,25−8.06=213.06,−23.06
Given: x2−5x−10=0Here, a=1,b=−5 and c=−10∴ D=b2−4ac=(−5)2−4×1×−10=65x=2a−b±D=2×15±65=25±8.06=25+8.06,25−8.06=213.06,−23.06x=6.53,−1.53.
