Answer 2

Here Is Your Ans ⤵

****

Ans :- X = $\fbox{2}$

Or X = $\fbox{ \frac{1}{7} }$

Given :-

➡7X² - 15X + 2 = 0

To Find :-

➡X = ?

Solution :-

➡D = B² - 4AC =(−15)² - (4 × 7 ×2)

➡D = B² - 4AC = 225 − 56

➡D = B² - 4AC = 169

$\implies X_{1} \: = \frac{ - b \: + \sqrt{d} }{2a} \\ \\ = > \frac{- ( - 15) + \sqrt{169}}{2 \times \: 7 } \\ \\ = > \frac{15 + 13}{14} \\ \\ = > \frac{28}{14} \\ \\ = > 2 \\ \\ \implies X_{2} = \frac{ - b \: - \sqrt{d} }{2a} \\ \\ = > \frac{- ( - 15) - \sqrt{169}}{2 \times \: 7 } \\ \\ = > \frac{15 - 13}{14} \\ \\ = > \frac{2}{14} \\ \\ = > \frac{1}{7}$

****

Hence , X = $\fbox{2}$

Or X = $\fbox{ \frac{1}{7} }$
