Solve X squared minus 8X +3 equals zero by completing the square which equation is used in the process?

x = 4 ± √13

Step-by-step explanation:

x² − 8x + 3 = 0

Complete the square.  (-8/2)² = 16.

x² − 8x + 16 − 13 = 0

(x − 4)² − 13 = 0

(x − 4)² = 13

x − 4 = ±√13

x = 4 ± √13

step-by-step explanation:

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
