Simplify 9x 5 - x 3?
I am trying to read this right: (9 x 5) - x3 = ? or 9 x (5 - x3) = ? Which one is it?
X3 plus x2 plus 5x plus 5?
10x + 5 unless you know what x & y are * * * * * Perhaps this answer will be of help: x3 + x2 + 5x + 5 = (x + 1)(x2 + 5). If you are willing to go to complex roots, then, x3 + x2 + 5x + 5 = (x + 1)(x2 + 5). = (x + 1)(x + i√5)(x - i√5); in which case, x = -1 or ±i√5.
How do you factor x3 plus 12x2-5x?

How do you factorise x3 plus 2x2-8x plus 5 equals 0?
x3 + 2x2 - 8x + 5 = 0 x(2x - 8) + 5 = 0
How do you factor x3 plus x2 plus x equals?
x3+x2+x First, factor out the x: x(x2+x+1) Could stop there, but the rest is factor-able using imaginary numbers: x(x+.5(1+i(3).5)(x+.5(1-i(3).5), where i = (-1).5, or sqrt(-1)
What is 5x plus 3 equal 28?
It is an equation of: 5x+3 = 28 and its solution is x = 5 5 times x plus 3 equals 28. Subtract 3 from both sides of the equation. 5 times x equals 25. Divide both sides of the equation by 5. x equals 5. (stop)
