One of the factor of x2 – 3x – 10 is :

x2 – 3x – 10 = 0x2 – 5x + 2x – 10 = 0x(x – 5) + 2(x – 5) = 0(x – 5)(x + 2) = 0 Hence, (x – 5) is a factor.

One of the factor of x² – 3x – 10 is :

x² – 3x – 10 = 0

x² – 5x + 2x – 10 = 0

x(x – 5) + 2(x – 5) = 0

(x – 5)(x + 2) = 0 Hence, (x – 5) is a factor.

If a polynomial p(x) is divided by (ax + b), then the remainder is:

If a polynomial x³ – ax² + ax – a is divided by (x – a), then the remainder is:

If (ax – b) is a factor of p(x) then,

One of the factor of x³ – 2x² + 2x – 1 is :
