Factor completely<br> B. (x+5)²-2(x+5)-24<br> C. (x+2)²-8(x+2)+15<br> D. 2(2x-1)²-9(2x-1)+4

Sladkaya [172]

B.
${x}^{2} + 10x + 25 - 2x - 10 - 24 = \\ x {}^{2} + 8x - 9 = \\ (x - 1)(x + 9)$

C.
${x}^{2} + 4x +4 - 8x - 16 + 15 = \\ x {}^{2} - 4x + 3 = \\ (x - 3)(x - 1)$
D.
$2( {4x}^{2} - 4x + 1) - 18x + 9 + 4 = \\ 8x {}^{2} - 8x + 2 - 18x + 13 = \\ 8x {}^{2} - 26x + 15$

The curve with equation y=e^2x/4+3e^x has one stationary point.find the exact value of the coordinates of this point

Softa [21]

$y=\dfrac{e^{2x}}{4+3e^x}$
$\implies y'=\dfrac{2e^{2x}(4+3e^x)-3e^xe^{2x}}{(4+3e^x)^2}$
$\implies y'=\dfrac{8e^{2x}+3e^{3x}}{(4+3e^x)^2}$

Stationary points occur where the derivative is zero. The denominator is positive for all $x$ , so we only need to worry about the numerator.

$8e^{2x}+3e^{3x}=e^{2x}(8+3e^x)=0$

$e^{2x}>0$ for all $x$ , so we can divide through:

$8+3e^x=0\implies e^x=-\dfrac83$

But $e^x>0$ for all $x\in\mathbb R$ , so this function has no stationary points...

I suspect there may be a typo in the question.
