$3 \times - {x}^{2} = - 3 {x}^{2}$
This, therefore:
${x}^{2} - 21 = 3 \left(5 - {x}^{2}\right) \to {x}^{2} - 21 = 15 - 3 {x}^{2}$

# How do you simplify ln e^(2x)?
Aug 25, 2016
$\ln {e}^{2 x} = 2 x$
#### Explanation:
As a Real valued function, $x \mapsto {e}^{x}$ is one to one from $\left(- \infty , \infty\right)$ onto $\left(0 , \infty\right)$.
As a result, for any $y \in \left(0 , \infty\right)$ there is a unique Real value $\ln y$ such tha... |

## Solving integration by the use of partial fractions
Solution:
(a) A=2, B=-5, C=0
(b) 2x/(x2+3)
(c) ln(2x-1) – (5/2)ln(x2+3) + C
(a)6 + 5x – 8x2 = A(x2 + 3) + (Bx + c)(2x – 1)
Sub x = ½
6 + 5/2 – 8(1/2)2 = A(1/4 + 3) + 0
13/2 = (13/4)A —— A=2
When x=0, 6 = 2(3) + c... |
