Question

Divide. Write the quotient and the remainder.

(21x4 − 14x2 + 7x) ÷ 7x3

Solution

(21x4 − 14x2 + 7x) ÷ 7x3

\[= \frac{21 x^4 - 14 x^2 + 7x}{7 x^3}\] 

\[ = \frac{7 x^3 \times 3x - 14 x^2 + 7x}{7 x^3}\] 

\[ = \frac{7 x^3 \times 3x}{7 x^3} + \frac{- 14 x^2 + 7x}{7 x^3}\] 

\[ = 3x + \frac{- 14 x^2 + 7x}{7 x^3}\]

So, quotient = 3x and remainder =

\[- 14 x^2  + 7x\]
  Is there an error in this question or solution?
