x2 plus 6x-2 equal -2x2 plus x ..
=7x equal -3x2 ..
4x=2
x=2 answer ..
check it if u dont want to trust ..
Improved Answer:
x2+6x-2 = -2x2+x
x2+2x2+6x-x-2 = 0
3x2+5x-2 = 0
(3x-1)(x+2) = 0
x = 1/3 or x = -2
The answer can be checked by using the quadratic equation formula.

What are the x-solutions for the equation below 10x2 - 56 equals 88 - 6x2?
10x2 - 56 = 88 - 6x2 : 10x2 + 6x2 = 88 + 56 : 16x2 = 144 : x2 = 9 : x = ± 3
Factor the polynomial x3-2x2 plus x-2?
x3 - 2x2 + x - 2 =(x - 2)(x2 + 1)
X2 plus 1 divided by 2x4 plus 4x3 -x2 plus 4x-3?
You can work this out with long division, by checking to see if (x2 - 1) is a factor of (2x4 + 4x3 - x2 + 4x - 3). It is. Unfortunately, the WikiAnswers system is somewhat limited in depicting things such as long division, so we won't be able to represent it here. In short though, (2x4 + 4x3 - x2 + 4x - 3) / (x2 + 1) is equal to 2x2 + 4x - 3. which means that: (x2 + 1) / (2x4 + 4x3 - x2 + 4x - 3) = (x2 + 1) / (x2 + 1)(2x2 + 4x - 3) = 1 / (2x2 + 4x - 3)
What does x2 plus x2 equals?
x2 + x2 = 2x2
What is x2 plus 7x equals - 2x2 plus 6 in the form ax2 bx c equals 0?
x2 + 7x = 2x2 + 6 x2 - 2x2 + 7x = 6 -x2 +7x - 6 = 0 or alternatively x2 - 7x + 6 = 0
How do you factor 6x3-x2 plus 17 equals 2x2 plus 47?
6x3 - x2 + 17 = 2x2 + 47 6x3 - x2 - 2x2 = 47 - 17 x2(6x - 1 - 2) = 30 this is the simplest factorisation.

What is X2 plus X2?
x2 + x2 = 2x2
How do you solve for x in the equation 3 over x square plus 3 over 4x minus 3 over 1 equals 6 over 2x square minus 6 over 3x plus 6 over 5?
3/(x2+4x-1) = 6/(2x2-3x+5) Cross - multiply in order to eliminate the fractions: 6*(x2+4x-1) = 3*(2x2-3x+5) 6x2+24x-6 = 6x2-9x+15 6x2-6x2+24x+9x = 15+6 33x = 21 x = 21/33 => x = 7/11
2x2 plus 42 equals x2 plus 13x?
This is a quadratic equation question which will have two answers: 2x2+42 = x2+13x 2x2-x2-13x+42 = 0 x2-13x+42 = 0 Factorising the equation gives you: (x-6)(x-7) = 0 Therefore: x = 6 or x = 7
What is X if 2X squared plus 10 equals 100?
If 2x2 + 10 = 100 then: 2x2 = 100 -10 2x2 = 90 x2 = 90/2 x2 = 45 x = 6.708 (to 3 decimal places only)
What is 3x-5x plus x2-6x2 simplified?
(3x - 5x) + (x2 - 6x2) = -2x -5x2 = -x(2 + 5x)
What are the x solutions for the equation 10x2 - 64 equals 36 plus 6x2?
10x2 - 64 = 36 + 6x2; whence, 4x2 - 100 = 0, x2 = 25, and x = ±5.
What is 2x squared plus x2 equal?
2x2 + x2 = 3x2
What is 2x squared plus 5x-4x squared plus x-x squared?
2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2
