Question

1. Draw a graph of given Polynomials? ii) x² - X-6​

Answer 1

$\huge{\underline{\red{\mathfrak{♡ANSWER♡}}}}$

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

Answer 2

Answer:

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:
