Question

help if possible?
Write x2 - 2x - 3 = 0 in the form (x - a)2 = b, where a and b are integers. (4 points)

(x - 4)2 = 3

(x - 3)2 = 2

(x - 2)2 = 1

(x - 1)2 = 4

Answer 1

\[\left(x-1\right)^2=4\]

Answer 2

subtract 3 on both sides
x^2 - 2x = -3
\[\mathrm{Add\:}\left(\frac{-2}{2}\right)^2\mathrm{\:\to\:both\:sides}\]
\[x^2-2x+1=4\]

\[\left(x-1\right)^2=4\]

Answer 3

thank you

Answer 4

wellcome :) @kinserkara
