Solve this quadratic equation. 6x^2 - 2x = 7

sweet-ann [11.9K]

The solutions to the equation are $\frac{1 +/- \sqrt{43}}{6}$ .

You can find the answer to any quadratic by using the quadratic formula. The formula is below.

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

Then find a (the number attached to x^2), b (the number attached to x) and c (the constant). This will allow you to plug in and solve.

$\frac{2 +/- \sqrt{-2^{2}-4(6)(-7)}}{2(6)}$

$\frac{2 +/- \sqrt{4 + 168}}{12}$

$\frac{2 +/- \sqrt{172}}{12}$

$\frac{1 +/- \sqrt{43}}{6}$

Write these numbers in size order start with the smallest

professor190 [17]

First convert all to decimal.

7/9 = 0.777
8/11 = 0.727
0.79 = 0.79
84% = 0.84
4/5 = 0.8

Now line them back up in order from least to greatest based on the decimal value.

Final answer:
8/11, 7/9, 0.79, 4/5, 84%
