Answer 2

$\bf\huge\gray{ANSWER}$

$\sf{→ a = 4 , \: b = 52 , \: c = -69}$

$\large\text \pink{Using above Formula}$

$\large \text{→ x = [-b ± √(b² - 4ac)]/2a }$

$\bf{put \: \: values,}$

$\sf{→ x = [-52 ±√(52)²-4×(4)×(-69)]/2×4}$

$\sf{→ x = ±√(2704 + 1104)]/8}$

$\sf{→ x = [-52 ± √(3808)]/8 }$

$\sf{→ x = [-52 ± 4√238]/8 }$

$\sf{→ x = 4[-13 ± √238]/8}$

$\sf{→ x = [-13 ± √238]/2}$

$\large\text\red{Final Answer}$

$\boxed{→ x = (-13 + √238)/2 \: \: and \: \: (-13 - √238)/2}$
