3x^2-10x-8

Give me some work with it. I'm lazy.

3x^2-10x-8
= 3x^2+2x-12x-18 (write it as a difference)
= x•(3x+2)-4(3x+2)
= (3x+2)• (x-4)

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425
