Question

Solve the equation below. 5x^2 − 7x + 8 = 2

Answer 1

Answer:

$\frac{7- \sqrt{71}i }{10}$

$\frac{7+ \sqrt{71}i }{10}$

Step-by-step explanation:

$5x^{2} - 7x + 6= 0$

By quadratic formula,

Given in this question a = 5,

                                   b = -7

                                    c = 6

x can be

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

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

Putting these values in the formula we get,

$x1 = \frac{7+ \sqrt{49 - 120} }{10}$

$x2 = \frac{7- \sqrt{49 - 120} }{10}$
