Question

2x2+5√3x+6=0 by quadratic formula

Answer 1

★ Answer :

We know that

D = b² - 4ac

→ D = (5√3)² - 4(2)(6)

→ D = 25 * 3 - 8(6)

→ D = 75 - 48

→ D = 27

$\rule{100}{2}$

Now,

x = -b ± √D/2a

→ x = -5√3 ± √27/2(2)

→ x = -5√3 ± 3√3/4

→ x = √3(-5 ± 3)/4

Putting positive.

→ x = √3(-5 + 3)/4

→ x = √3(-2)/4

→ x = -√3/2

Or

Putting negative

→ x = √3(-5 - 3)/4

→ x = √3(-8)/4

→ x = -2√3

Answer 2

Answer is: -√3/2 , -2√3..

hope this help you

if yes mind it as brilliant answer!!❤️❤️
