Question

`- 9x ^(2) + 49 = 0`find the solution of the quadratic equation

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

-9x² + 49 = 0

x = ?

Step 02:

quadratic equation:

-9x² + 49 = 0

-9x² = - 49

x² = -49 / -9

x² = 49/9

`\begin{gathered} x\text{ = }\sqrt[]{(49)/(9)}\text{ } \\ x1\text{ = }\frac{7}{3\text{ }} \\ x2\text{ = - }(7)/(3) \end{gathered}`

The answer is:

x1 = 7/3

x2 = - 7/3
