Answer 2

Answer:

$- 7 \sqrt{5}$

Step-by-step explanation:

as we know,

zeros make the quadratic equation also equal to zero thus,

$p(x) = 7 \sqrt{15} \ + \sqrt{3} x = 0 \\ \\ \\ \\ 7 \sqrt{15} + \sqrt{3} x = 0 \\ \sqrt{3} x = - 7 \sqrt{15} \\ x = \frac{ - 7 \sqrt{15} }{ \sqrt{3} } \\ x = \frac{ - 7 \times \sqrt{5} \times \sqrt{3} }{ \sqrt{3} } \\ x = - 7 \sqrt{5 } \\ \\ therefore \\ x = - 7 \sqrt{5} \\ x + 7 \sqrt{5} \: will \: be \: the \: zero \: which \: will \: make \: it \: equal \: to \: zero$

hopefully it will be helpful to you !!!
