Question

y3 - 39y - 70 ; y+ 2 remainder theorem​

Answer 1

Answer:

if you want to find remainder with remainder theorem

remainder theorem : Dividend= divisor× quotient+remainder

firstly you find the value x then the value of y+22 becomes zero

therefore, -2 is the value that make the divisor 0

then when we multiply divisor× quotient the all term get zero

then we have the remaining term

y^3-39y-70= remainder

then put the y = -2

-2^3-39×(-2)-70 = remainder

-8+78-70= remainder

0 is the remainder
