• x = 0 when equation equals to 5

★ To Find :-

• Value of k

$\large\blue{\underline{\texttt\pink{★ \: Solution :-}}}$

According to the given question,

☞ x² – 5x + k = 5

☞ (0)² – (5 × 0) + k = 5

☞ 0 - 0 + k = 5

$\large\blue{\sf\pink{\therefore{ \: k = 5}}}$

Then,

(d) 5 will be your required answer!!

Answer 2
