2x2=4 x2=8 x2=16 x2 = 32 and 5x5 = 25 so no, I guess not.
x2 + x2 = 2x2
x2 + x2 = 2x2
2x4
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)
x2 - (2x)2 = x2 - 4x2 = -3x2 x2 - 2x2 = -x2
2x2 + x2 = 3x2
Reading this as: 4x2-6=2x2 This implies that: -6=-2x2 3=x2 x=sqrt(3) and x=-sqrt(3) So x can equal plus or minus the square root of 3
x2 + x2 = 2x2 2x^2
2x2=4 x2=8 x2=16 x2 = 32 and 5x5 = 25 so no, I guess not.
2x2 + 2x - 8 = 2(x2 + x - 4). This can take any value greater than or equal to -8.5
The question is ambiguous and two possible answers are given below: 2x2 - x2 = x2 or (2x)2 - x2 = 4x2 - x2 = 3x2
x2 + x2 = 2x2
x2 + x2 = 2x2
x2+xx = 15 Which is the same as: x2+x2 =15 2x2 = 15 x2 = 7.5 x = the square root of 7.5
x2 + x2 = 48 2x2 = 48 x2 = 24 x = √24 x = 2√6
6x3 - x2 + 17 = 2x2 + 47 6x3 - x2 - 2x2 = 47 - 17 x2(6x - 1 - 2) = 30 this is the simplest factorisation.
