What is x plus 2x plus 14 equals 5x plus 2?
x+2x+14=5x+214-2=5x+2x+x10=8x10/8=xx=5/4 ans.
What is xx plus 2x plus 3x plus 6 equal to?
X can't be solved, you don't have anything on the right side of the equal.
What is -0.5x2 plus 2x plus 10?
Doesn't factor evenly, use quadratic -.5xx+2x+10 -.5(xx-4x-20) No factors of -20 add up to -4
What is the solution of the equation of 4x equals 2x plus 14?
First, write it in a mathematical equation form:4x=2x+14Next, subtract 2x from both sides2x = 14Divide both sides by xx = 7
What is IXX squared showing all your working?
IXX (19) squared = -I(-I+XX)+XX(-I+XX) Multiplying out brackets = +I-XX-XX+CCCC Collecting like terms = -XXXX+CCCC+I (401-40) Then when simplified = CCCLXI (361) which is the correct answer. Remember that in maths a minus number multiplied by a minus number produces a plus number. Thus -I times -I is +I. David Gambell, Merseyside, England.
Is 9X2-18X plus 36 a perfect square?
No 9xx-18x+36 9(xx-2x+4) xx-2x+4 (doesn't factor evenly)
What is x plus 2x plus 14 equals 5x plus 2?

How do you factor x squared plus two x plus three?
Unfortunately, you can't. If it were x2 + 2x - 3 ... you could factor it into (x-1)(x+3). Hope I helped!xx MorganAdded:X =[ - 2 (+/-) sqrt(- 8)]/2would be the answer in complex fashion and and i, imaginary number answer would be forthcoming.

What does xx mean in math?
x times x, (x)(x), or x squared
X squared plus xx is equal to 15?
x2+xx = 15 Which is the same as: x2+x2 =15 2x2 = 15 x2 = 7.5 x = the square root of 7.5
6x to the power of 2 over 2x to the power of 2?
If you mean (6x^2)/(2x^2), this problem is easy. (6x^2)/(2x^2) = (6/2) x (XX/XX) (XX is an easy way of writing X^2) 6/2 = 3 XX/XX = 1 3 x 1 = 3 so your answer is 3.
What is 3x equals x squared minus 2x?
3X = x2 - 2xsubtract 3X from each sideX2 - 5X = 0factor out an XX(X - 5) = 0=========X = 0--------orX = 5--------
How is x to the power of x defined mathematically correctly?
xx or 2x.
