Question

Q21. Find zeroes of polynomial x² -7x +6 and veryfy the relationship between the zeroes and the coefficients​

Answer 1

Answer:

hope it helps :)

do mark my answer as brainliest :)

Explanation:

x

2

−x−6=0

⇒x

2

−3x+2x−6=0

⇒x(x−3)+2(x−3)=0

⇒(x+2)(x−3)=0

⇒x+2=0,x−3=0

⇒x=−2,x=3

Hence, the zeroes of the polynomial x

2

−x−6=0 are 3,−2.
