x3 + 2x2 - 8x + 5 = 0 x(2x - 8) + 5 = 0
If your question was 2X + 5 =10. X equals what? Then X=2.5
2x-11
(x + 5)(x^2 + 2x + 2)
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
x3 + 2x2 - 8x + 5 = 0 x(2x - 8) + 5 = 0
Yes.
x^3=2x+5 x^3-2x-5=0 Graph the equation or use a calculator. x= 2.09455148
If your question was 2X + 5 =10. X equals what? Then X=2.5
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
2x-11
(x + 5)(x^2 + 2x + 2)
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
3x+5 = 2x+13 3x-2x = 13-5 x = 8
x equals 4
2x+2=x+5 x=3
4x - 5 + 2x = 37
