Solve the expression x2 – 2x - 8 = 0 by completing the square. (A)X = 1+13
(B) x = 1+V3
(C) x = 4, X = 2
(D) x = 4, X =-2

answer is option D , x = 4 , x = -2 is the correct answer of this question

plz mark my answer as brainlist pl vote me also

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
