Factorize the following algebraic expression:

Hoochie [10]

X^2+16-38=0
find what 2 numbers multiply to get -38 and add to get 16
find factors of 38
2 times 19
there is no way to use common factor so use quadratic formula which is
x= $\frac{ -b+\sqrt{b^2-4ac} }{2a}$ or x= $\frac{ -b-\sqrt{b^2-4ac} }{2a}$

ax^2+bx+c=0 subsitte
a=1
b=16
c=-38
subsitute
$\frac{ -16+\sqrt{16^2-4(1)(-38)} }{2(1)}$ = $\frac{ -16+\sqrt{256+152} }{2}$ = $\frac{ -16+\sqrt{408} }{2}$ = $\frac{ -16+2\sqrt{102} }{2}$ = $-8+\sqrt{102}$
so the answers for x are $-8+\sqrt{102}$ and $-8-\sqrt{102}$ which are aprox -2.099504938362 and +18.099504938362
so it would be
(x-[-8+√102])(x+[8+√102])=0

What is 12/24 - 10/23

Elodia [21]

The LCD of 24 and 23 is 552, so 276/552 - 240/552 = 36. After simplifying 36/552, you get 3/46 and that is your answer.

Solve to inequality 5/6v < 8/5

Anna35 [415]

$\dfrac{5}{6}v \ \textless \ \dfrac{8}{5}\ \ \ |multiply\ both\ sides\ by\ \dfrac{6}{5}\\\\\dfrac{6}{5}\cdot\dfrac{5}{6}v \ \textless \ \dfrac{6}{5}\cdot\dfrac{8}{5}\\\\v \ \textless \ \dfrac{48}{25}\to v\in\left(-\infty;\ \dfrac{48}{25}\right)$
