- 2X - 2 = 4 ?
If so.....,
- 2X - 2 = 4
add 2 to each side
- 2X = 6
divide each sides integers by - 2
X = - 3

-2x - 2 = 4-2x = 4 + 2-2x = 6x = 6/-2x = -3Check:-2(-3) - 2 = 46 - 2 = 44 = 4
2x + 4 = 2 2x = -2 x = -1
Divide both sides by two. x = 2 2x=4 2x/2=4/2 2x/2=1x=x 4/2=2 x=2
-2x - 10 + 4 = 2 -2x - 6 = 2 -2x = 2 + 6 -2x = 8 -x = 8 / 2 x = -4 Check: -2(-4) - 10 + 4 = 2 8 - 10 + 4 = 2 8 - 6 = 2 2 = 2
Do you mean '16x^(4) -1 ; or ' (16 X 4 ) - 1' . Reason , the answers will be different. 16x^(4) - 1 = (2x)^(4) - 1^(4) = ((2x^(2) - 1^(2))((2x)^(2) + 1^(2)) = (2x - 1)(2x +1)((2x)^(2) + 1^(2)) = (2x - 1)(2x + 1)((2x)^(2) + 1) 2 & ( 16 X 4 ) - 1) = 64 - 1 = 63
