Question

1. Draw the graph of y = x2 – 2x – 3 and find zeroes. What do you notice. . -
​

Answer 1

Answer:

The answer the zeros of the equation are 3 and -1

Step-by-step explanation:

The graph is in the picture.

x²-2x-3 = 0

Or, x²-(3-1)x-3 = 0

Or, x²-3x+x-3 = 0

Or, x(x-3)+(x-3) = 0

Or,(x+1)(x-3) = 0

Either, x+1 = 0

Or, x = -1

Or, x-3 = 0

Or, x = 3
