Question

the x co ordinates of the points where the graph of y=x² -6x+8 intersects the x axis are

Answer 1

Answer:

Step-by-step explanation:

Since, it is interesting x-axis.

Therefore, ordinate is 0.

y=0

Putting the value of y in y= x^2-6x+8

0=x^2-6x+8

By middle term splitting method,

x^2-4x-2x+8= 0

x(x-4)-2(x-4)= 0

(x-4)(x-2)= 0

x-4=0

x= 4

Also, x-2= 0

x= 2

Answer 2

Answer: it intersects x axis at two pints (2,0) and (4,0)

Step-by-step explanation:

For intersect x axis y=0 .then x^2-6x+8=0 . It give x=2,4.
