Question

Find the root of the equation 5x²-6x-2=0​

Answer 1

$\huge{\underline{\underline{\boxed{\sf{\purple{Answer}}}}}}$

5x² -6x -2 = 0

a = 5

b = -6

c = -2

By using quadratic formula :

x = -b ± √b² - 4ac / 2a

x = -(-6) ±√(-6)² -4(5)(-2)/2(5)

x = 6 ± √36 + 40 / 10

x = 6 ± √76/10

x = 6 ± 2√19/10

x = 2(3 ± √19)/10

x = 3 ± √19/ 5

x = 3 + √19/5, 3-√19/5

3+√19/5 and 3-√19/5 are the roots of the given quadratic equation.
