#### Sir, Can you please solve the following:- If the polynomial X4- 6X3+16X2-25X+10 is divided by another polynomial X2-2X+k, the reminder is X+a . Find k and a



Answer.

Given that the remainder is (x + a)
⇒ (4k – 25 + 16 – 2k)x + [10 – k(8 – k) ] = x + a
⇒ (2k – 9)x + [10 – 8k + k<...

#### If α  and  β are zeroes of the polynomial x2-4x+3 , then form quadratic polynomial whose zeroes are (1) 3αand 3β           (2)1/2α   and  1/2β



Sol:
Given  α and β are zeroes of the polynomial f(x) = x2- 4x + 3

α+ β = 4 αβ = 3

1) (3α + 3β) = 3x 4 = 12
