Question

Which are the zeroes of p(x) = (x –6)(x +2)

Answer 1

Step-by-step explanation:

We find the zeroes by factorizing the equation x

2

−x−6=0 as follows:

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.
