Answer 2

$\bigstar$ Correct Question:

• Divide 4x³ - 3 + x² + 52x - 15 by 4x - 5 and write down the remainder.

$\star$ To find:

• Find out the remainder when 4x³ - 3 + x² + 52x - 15 is divided by 4x - 5.

$\star$ Solution:

We have,

p(x) = 4x³ - 3 + x² + 52x - 15

= 4x³ + x² + 52x - 18

So, by using using remainder theorem,

we get 4x - 5 = 0

$\implies$ 4x = 5

$\implies$ x = 5/4

Now, we will have to put the value of x in p(x).

$\therefore$ p(5/4)

= 4(5/4)³ + (5/4)² + 52(5/4) - 18

= 125/16 + 25/16 + 65 - 18

= (125 + 25)/16 + 47

= 150/16 + 47

= 75/8 + 47

= 75/8 + 376/8

= 451/8

• Therefore the remainder is :
• $\frac{451}{8} \: or \: 5 \frac{5}{8}$

$\bigstar$Answer:

Therefore the remainder is 451/8
