2x2 ÷ x = 2x
You should square root both the top and bottom of the equation, which would give you (β2x)/x.
x + 1
(-2x2 + x + 1) / (x - 1) = (-2x - 1)(x - 1)/(x - 1) = -2x - 1
Numerator = (x + 4)*(x + 3) Denominator = (2x - 1)*(x + 3) Calcelling out the common factor, (x + 3), the answer is (x + 4) divided by (2x - 1) provided x ≠0.5
2x to the fourth
- ln ((x^2)-4)
3x squared - x squared = 2x squared
4
No. x squared is x times x, whereas 2x is x + x.
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
The quotient works out as: x^2+2x+4 and there is a remainder of -3
