Answer:

x = 3.235 or -1.235

Step-by-step explanation:

y = 1 (given)

y = x² -2x -3

So,

1 = x² -2x -3

=> x² -2x -4 = 0

a= 1, b = -2, c = -4

So, Now,

x = (-b ± √b²-4ac)/2a

=> x = ( -(-2) ± √(-2)² -(4)(1)(-4) ) /2(1)

=> x = (2 ± √20 )/2

=> x = (2 ± 4.47 )/2

=> x = 6.47/2 | x = -2.47/2

=> x = 3.235. | x = -1.235

So, That Gives Us The Value Of x as 3.235 or -1.235

Hence, x = 3.235 or -1.235
