Q3 of 86 Page 42

Find the remainder when 2x2 – 3x + 5 is divided by 2x – 3. Does it exactly divide the polynomial? State reason.

Let p(x) = 2x2 – 3x + 5


As we know by Remainder Theorem,


If a polynomial p(x) is divided by a linear polynomial (x – a) then, the remainder is p(a)


Remainder of p(x) when divided by 2x – 3 is




Remainder of 2x2 – 3x + 5 when divided by 2x – 3 is


As on dividing the given polynomial by 2x – 3, we get a non–zero remainder, therefore, 2x – 3 does not complete divide the polynomial.


It is not a factor.
