Question

find remainder when
$y { }^{3} + y {}^{2} - 2y + 5 \: is \: divided \: by \: y - 5$
​

Answer 1

Answer : 145

Step-by-step explanation:

Method 1. By Remainder theorem

zero of the polynomial g(x) = y - 5 = 0, y = 5

Now,

put the value of x in the polynomial p(x)

${5}^3 + {5}^2 - 2 {(5)} + {5}$

= 125 + 25 - 10 + 5

= 145
