p2 + 13p – 30 = 0

p%5E2+%2B+13p+-+30+=+0

Looking for 2 factors that when multiplied gives us -30 (c * a), and when added, gives us + 13 (b). These 2 factors are "+ 15" and "- 2."

Therefore, we have:

(p + 15)(p - 2) = 0

p + 15 = 0, or p - 2 = 0

Therefore, p = highlight_green%28-15%29 or highlight_green%282%29
