First set everything to 0.

Giving you A= 1 , B= 1 and C= -5
Then input everything into the quadratic formula and either solve by hand or use a calculator.
Note exact values are found by hand, decimals are found using a calculator.
The answer is -403
The order of operations puts multiplication before subtraction. -1 x 372= -372, and -372-31= -403
