Question

*If y³+y²-3y+1 is divided by (y+2) then find remainder by using remainder theorem .* 1️⃣ 1 2️⃣ 3 3️⃣ 7 4️⃣ -5​

Answer 1

Step-by-step explanation:

The remainder theorem formula is: p(x) = (x-c)·q(x) + r(x). The basic formula to check the division is: Dividend = (Divisor × Quotient) + Remainder.

y+2=0 so y= -2

p(y)=y3+y2-3y+1

p(-2)=(-2)^3+(-2)^2-3*(-2)+1=-8+4+6+1=3

it would be your humble consideration to mark me as the brainliest.
