Question

5x²-7x-3= 0 by quadratic formulae​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Quadratic formula, x $= \frac{ - b ± \sqrt{ {b}^{2} - 4ac} }{2a}$

The given equation is, 5x² - 7x - 3 = 0

where a = 5, b = -7, c = -3

$x = \frac{ - ( - 7)± \sqrt{ { - 7}^{2} - 4(5)(-3) } }{2 \times 5}$

$x = \frac{ 7± \sqrt{49+60 } }{10} </p><p> = \frac{7± \sqrt{109} }{10}$

$x = \frac{7 + \sqrt{109} }{10} ; \: x = \frac{7 - \sqrt{109} }{10}$
