Solve by using the quadratic formula: x^2 - 6x + 7 = 0 Please enter any square root values using "sqrt" or the decimal answer ro
olga nikolaevna [1]

Given parameters:

 Quadratic expression:

                 x² - 6x + 7 = 0

Solve using quadratic formula;

                      x   = \frac{-b +/- \sqrt{b^{2 } - 4ac} }{2a}

From the equation;

  a  = 1, b = -6 and c = 7

Input the parameters and solve;

           x = \frac{-(-6) +/- \sqrt{-6^{2 } + 4 x 1 x 7 } }{2 x 1}

          x = \frac{6 +/- \sqrt{36} +28 }{2}

        x = \frac{6 +/- \sqrt{64} }{2}

          x = \frac{6 + 8}{2 }    or \frac{6-8}{2}

          x = 7 or -1

What fraction makes this division<br> sentence true? <br> 2/3 divided by ? = 4
NeX [460]

Answer:

1/6

Step-by-step explanation:

The opposite of dividing by a fraction is multiplying by the inverse of the fraction. So, to find out what fraction to divide by you need to find what number you need to multiply 2/3 by to get 4.

2/3 x 6 = 4

So if you want to divide instead of multiply, just find the inverse of the number you are multiplying by.

The inverse of 6 is 1/6. Therefore, 2/3 divided by 1/6 equals 4.

(2/3)/(1/6) = 4

For (x - 1)(x - 7) to equal 0, either (x - 1) or (x - 7) must equal what?
Kisachek [45]
(x - 1)(x - 7) = 0

{x}^{2} - 8x + 7 = 0

{x}^{2} - 8x = - 7

- 7x = \frac{ - 7}{x}

x = \frac{ - 7}{ \frac{x}{ - 7} } \implies x = x \implies x \in \mathbb{R}

x is true for any number in real domain.
