Question

x2-x-6 in graphically

Answer 1

Answer:

(x-3) (x+2) is the answer for this question

Answer 2

Answer:

Clearly graph of y=x2−x−6cut the x-axis at x=−2,3.

⇒Clearly graph of y=x 2

−x−6 cut the x-axis at x=−2,3.

⇒x=−2,3 are zeros of y=x

2

−x−6.

Justification:

when x=−2;y=4+2−6=0

when x=3;y=9−3−6=0=−2,3 are zeros of y=x

2

−x−6.

Justification:

when x=−2;y=4+2−6=0

when x=3;y=9−3−6=0
