Question

check wheather 3 is zero of the polynomial p(x) =x²-x-6​

Answer 1

Step-by-step explanation:

3×3 -3-6

9-9

0

it is coming equal to zero.

so, 3 is zero of the polynomial

Answer 2

Answer:

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

.

Therefore, 3,−2 is your answer...
