Question

Answer 1

Hey Friend ✌
Here is ur Ans ⤵️⤵️⤵️


$x {}^{2} + 3x + 12 = 0$

$using \: \: quadrictic \: \: formula \: \:$

$x = \frac{ - ( - 3 + - \sqrt{( - 3) {}^{2} - 4(1)( - 12) } }{2(1)}$

$x = \frac{3 + - \sqrt{9 + 48} }{2}$

$x = \frac{3 + \sqrt{57} }{2} \\ \\ \\ = 5.275$


$x = \frac{3 - \sqrt{57} }{2} \\ \\ = - 2.275$

Ans is ➡️ 5.275 & ( - 2.275 )
