Question

a) Find the zeroes of x2

– x – 12 graphically.

(OR)

b) Find the zeroes of x2

– 6x + 9 graphically.​

Answer 1

Answer:

y= x^2-x-12

Using Graphical method we see that when,

x=1,y= -11

x=2,y= -10

x=4, y=0

x= -1, y= -10

x= -3 , y=0

Then, we see that -3 and 4 are the zeroes of the polynomial

Use the same formula for the second question
