Solve for the equation for all x values by completing the square x^2 - 27= 67

navik [9.2K]

Answer:

The solutions for the equation $x^2\:-\:27=\:67$ are $x=\sqrt{94},\:x=-\sqrt{94}$ .

Step-by-step explanation:

To find the solutions for the equation $x^2\:-\:27=\:67$ you must:

$\mathrm{Add\:}27\mathrm{\:to\:both\:sides}\\\\x^2-27+27=67+27$

$\mathrm{Simplify}\\\\x^2=94$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}\\\\x=\sqrt{94},\:x=-\sqrt{94}$

Which expressions are equivalent to the one below? Check all that apply.<br><br>log 2 - log 6

Marina CMI [18]

Answer:

Given the expression: log 2 -log 6

Use the logarithmic rule :

$\log(\frac{m}{n}) = \log m - \log n$

$\log x^n = n\log x$

Use the above rule to solve the expression:

$\log 2 -\log 6 = \log \frac{2}{6} = \log \frac{1}{3}$ [∴ $\log(\frac{m}{n}) = \log m - \log n$ ]

$\log 2 -\log 6 =\log 2+ \log 6^{-1} = \log 2 + \log \frac{1}{6}$ [∴ $\log x^n = n\log x$ ]

value of : log 2 -log 6 = 0.30102999566 - 0.77815125038 = -0.47712125472
