To solve for a variable, you need to get it (x) by itself.

x² - 14 + 31 = 63   Add 31 to -14
x² + 17 = 63   Subtract 17 from both sides of the equation
x² = 46   Square root both sides
x = \pm \sqrt{46}

Check your work by plugging in \sqrt{46} for x and then - \sqrt{46}.

\sqrt{46}² - 14 + 31 = 63   Square \sqrt{46}
46 - 14 + 31 = 63   Subtract 14 from 46
32 + 31 = 63   Add
63 = 63

- \sqrt{46}² - 14 + 31 = 63   Square - \sqrt{46}
46 - 14  + 31 = 63   Subtract 14 from 46
32 + 31 = 63   Add
63 = 63

So, x is \sqrt{46} and - \sqrt{46} .

Which function in vertex form is equivalent to f(x) = x² + x +1?
mylen [45]

Answer:

\left( x+\frac{1}{2} \right)^{2}  + \frac{3}{4}

Step-by-step explanation:

NOTE :

x^2+ax=\left( x+\frac{a}{2} \right)^{2}  -\left( \frac{a}{2} \right)^{2}

………………………………………

f(x) = x² + x +1

     =x^{2}+2\times \frac{x}{2} +1

     =\left( x+\frac{1}{2} \right)^{2}  -\left( \frac{1}{2} \right)^{2}  +1

     =\left( x+\frac{1}{2} \right)^{2}  - \frac{1}{4}+1

     =\left( x+\frac{1}{2} \right)^{2}  + \frac{3}{4}
