Answer:
x = (-5 ± 2√10) / 3
Step-by-step explanation:
5 − 10x − 3x² = 0
Write in standard form:
-3x² − 10x + 5 = 0
Solve with quadratic formula:
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-10) ± √((-10)² − 4(-3)(5)) ] / 2(-3)
x = [ 10 ± √(100 + 60) ] / -6
x = (10 ± 4√10) / -6
x = (-5 ± 2√10) / 3

Answer:
see below
Step-by-step explanation:
First determine how much is subtracted from the account
12.57+24.95+36.86 =74.38
They charge .15 per check=3*.15 = .45
Subtract the amounts of the checks and the check fees
139.50-74.38-.45 =64.67
