Answer 1

Answer:

By long division as shown

AS Remainder should be zero ⇒ k=−10

Other two zeroes would be obtained by Qiotient

x

2

−3x+2=0

x

2

−2x−x+2=0

x(x−2)−1(x−2)=0

(x−1)(x−2)=0

x=1,2

Answer 2

Answer:

By long division as shown

AS Remainder should be zero ⇒ k=−10

Other two zeroes would be obtained by Qiotient

➡${x}^{2} - 3x + 2 = 0$

➡${x}^{2} - 2x - x + 2 = 0$

➡$x(x - 2) - 1(x - 2) = 0$

➡$(x - 1)(x - 2) = 0$

➡$x = 1 , 2$
