How do you factor the equation -x3 6x2-9x?
-x(x - 3)(x - 3)
What are the roots of x3 plus 3x2-9x plus 5?
x3 + 3x2 - 9x + 5 = 0 has roots of -5,1 and 1. CHECK : x3 + 3x2 - 9x + 5 = (x + 5)(x - 1)(x - 1)
Factor x to the fourth power plus 2x to the third power minus 9x to the second power plus 18x?
x4 + 2x3 - 9x2 + 18x = x(x3 + 2x2 - 9x + 18) which I do not think can be factorised further.
Factor 9x cubed plus 27x squared -90x?
Step 1: Divide by 9x: 9x (x2 + 3x - 10) = 9x(x + 5)(x - 2)
Who can factor 9x squared plus 8x -1?
9x2 + 8x - 1 = (9x - 1)(x + 1)
How do you factor x3-729?
(x - 9)(x2 + 9x + 81)
How do you factor the equation -x3 6x2-9x?
-x(x - 3)(x - 3)
What are the roots of x3 plus 3x2-9x plus 5?
x3 + 3x2 - 9x + 5 = 0 has roots of -5,1 and 1. CHECK : x3 + 3x2 - 9x + 5 = (x + 5)(x - 1)(x - 1)
How do you simplify x cubed- 9x?
To simplify x3-9x, you factor out the x, leaving you with x(x2-9). You can then take the square root of both numbers and end up with x(x+3)(x-3).
Factor x to the fourth power plus 2x to the third power minus 9x to the second power plus 18x?
x4 + 2x3 - 9x2 + 18x = x(x3 + 2x2 - 9x + 18) which I do not think can be factorised further.
How do you factor 3x2-9x?
factor out a 3x 3x(x-3)=3x2-9x
Factor 81x plus 9x?
You don't need to factor that; you can add them together, since they have the same variable.However, assuming you might mean 81x squared + 9x, you can take out the common factor, which is 9x.
What is factor x3-343?
x3-343
What is the factor of x to the power of 3-3x to the power of 2-9x plus 27?
x3 - 3x2 - 9x + 27 = x2(x - 3) - 9(x - 3) = (x - 3)(x2 - 9) = (x - 3)(x - 3)(x + 3)
How do you factor 9x squared-18?
I hope you mean x3+2x2-9x+18. Treat the equation like two equations: x3+2x2 and 9x+18. Factor out x2 from the first equation, so x2(x+2). Factor out 9 from the second equation, so 9(x+2). Now, the whole equation. x2(x+2)-9(x+2). Factor out (x+2), so (x+2)(x2-9). (x2-9) factors into (x+3)(x-3). So, (x+2)(x+3)(x-3) is the complete factorization. Hope this helps.
How do you factor x2-9x?
x2-9x = x(x-9)
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?
