In how many points will the graph of x² + 8x + 15 intersect X-axis ? Why

$\huge\bold\purple{♡} {\orange{\underline{\pink{\mathbf{ Solution}}}}} \bold\purple{♡}$

We can write x² + 8x + 15 as

x² + 5x + 3x + 15

➡ (x + 5) (x + 3)

So its zero values are -5, -3.

So the graph of x² + 8x + 15, intersect X-axis at two points only
