Add the expression: (3/2)x3 – (1/4)x2 + (5/3), (-5/4)x3 + (3/5)x

1.	Add the expression: (3/2)x3 – (1/4)x2 + (5/3), (-5/4)x3 + (3/5)x2 – x + (1/5), -x2 + (3/8)x – (8/15)
Answer» (3/2)x³ – (1/4)x² + (5/3), (-5/4)x³ + (3/5)x² – x + (1/5), -x² + (3/8)x – (8/15) Required sum, = (3/2)x³ – (1/4)x² + (5/3), (-5/4)x³ + (3/5)x² – x + (1/5), -x² + (3/8)x – (8/15) Collecting like terms, = [(3/2)x³ – (5/4)x³] + [- (1/4)x² + (3/5)x² -x²] + [– x + (3/8)x] + [(5/3) + (1/5) – (8/15)] = (1/4)x³ – (13/20)x² – (5/8)x + (4/3)

Add the expression: (3/2)x3 – (1/4)x2 + (5/3), (-5/4)x3 + (3/5)x2 – x + (1/5), -x2 + (3/8)x – (8/15)

Answer»

(3/2)x³ – (1/4)x² + (5/3), (-5/4)x³ + (3/5)x² – x + (1/5), -x² + (3/8)x – (8/15)

Required sum,

= (3/2)x³ – (1/4)x² + (5/3), (-5/4)x³ + (3/5)x² – x + (1/5), -x² + (3/8)x – (8/15)

Collecting like terms,

= [(3/2)x³ – (5/4)x³] + [- (1/4)x² + (3/5)x² -x²] + [– x + (3/8)x] + [(5/3) + (1/5) – (8/15)]

= (1/4)x³ – (13/20)x² – (5/8)x + (4/3)
