Question 124419: Can someone please help me.
(7/10x^3-3/10x-1/8)-(-1/10x^3+3/10x-1/8)
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
(7/10x^3-3/10x-1/8)-(-1/10x^3+3/10x-1/8)
= [(7/(10x^3)-(3/10x)- (1/8)] - [(-1/x^3)+(3/10x)-(1/8)]
= (8/x^3)- (6/10x)
lcd = 10x^3
= (80/lcd) - (6x^2/lcd)
= [80-6x^2]/10x^3
= [40-3x^2]/5x^3
