回答 (9)
✔ 最佳答案
4x = -36
x = -36/4
x = -9
divide 4 on each side.
x=-9
factoring or solving for x?
x = -9
4x + 36 = 0
4( x + 9 ) =0
( 2 + 2 )( x + 9 ) = 0
Not a lot of information about the goal -
4x = -36
Dividing by 4
x = -9
The factors of 4x are +/- 1, +/- 2, +/-4, +/-x +/-2x, +/-4x
-
The factors of -36 are +/-1,+/-2+/-3,+/-4,+/-6,+/-9,+/-12,+/-18,+/-36
參考: Retired math teacher
4x = -36
-36 / 4 = -9
you divide)
