When you divide 2x^3+7x^2+13x-3 by (x+1)^2 the remainder is of the form R(x) = r1x + r0
So 2x^3+7x^2+13x-3 = (x+1)^2 Q(x) + r1x + r0 ..........................(a)
When x = -1, this becomes 2 (-1)^3 + 7 (-1)^2 + 13 (-1) - 3 = 0 + r1 (-1) + r0
So -2 + 7 -13 - 3 = -r1 + r0
which is - 11 = -r1 + r0 .....................(b)
Now differentiate (a)
6x^2+14x + 13 = 2 (x+1) Q(x) + (x+1)^2 Q'(x) +r1
Now let x = -1
6 (-1)^2 + 14 (-1) + 13 = 0 + 0 + r1
Therefore r1 = 5
Hence from (b) r0 = -6
Hence the remainder when 2x^3+7x^2+13x-3 is divided by (x+1)^2 is = r1x + r0 = 5x - 6
This is exactly what I wrote before without the spoonfeed to let you THINK.

ශේෂ ප්රමේය නැවත නැවත පාවිච්චි කරන්නෙ... This is exactly I asked before what's meant by this. I am not aware of such a thing. Sorry.
To find the remainder there a only a few ways, standard long division, then synthetic division and finally the remainder theorem. (there are others like using the Taylor series which can generalize the remainder when divided by (x-a)^m, but they are beyond the scope of A/L)
The remainder theorem states....
Let P(x) be a polynomial of degree n. If P(x) is divided by x-a , where 'a' is a real number then the remainder is P(a)
Note that the divisor has be linear.
The remainder theorem can be extended to quadratic divisors
Let P(x) be a polynomial of degree n. If P(x) is divided by (x-a)(x-b), where both a & b are real, the remainder is of the form
R(x) = r1 x + r0 where both r0 & r1 are constants and found by solving
P(a) = r1 a + r2 & P(b) = r1 b + r2
Note - This doesn't work when the divisors are the same... (x-a)(x-a) or (x-a)^2
Hence AFAIK the derivative has to be used to solve for r0 and r1.

මේකෙ දෙවනි පේලිය ලියල තියෙනවා වැරදියි. (හැබැයි හරි දේ ඔලුවෙ තියාගෙන ලියල තියෙන්නෙ) බලන කෙනෙකුට පැටලෙන්නෙ එ්කයි. Keyboard එකේ theta නැති නිසා @ දාල කියන්නම්.
