X - the rate charged by the first mechanic
y - the rate charged by the second mechanic
The sum of the two rates was $155.

The first mechanic worked for 10 hours, the second mechanic worked for 5 hours, and together they charged $1000.

Set 155-x and 200-2x equal to each other:

The rate charged by the first mechanic was $45, and the rate charged by the second mechanic was $110.

Answer:
(7u+1)(2u-5)
Step-by-step explanation:
miltiply the coefficient of u² and the integer -5 = -70
from basic intuition: factors are -35 and +2
(which when added gives -33 and multiplies to give 70)
14u² -35u +2u -5
7u(2u-5) +1(2u-5)
(7u+1)(2u-5)
