Find the value or values of p in the quadratic equation p2 + 13p – 30 = 0. A. p = –10, p = –3 B. p = –15, p = 2 C. p = 10, p = 3 D. p = 15, p = 2
p^2 + 13p – 30 = 0 (p - 2)(p + 15) = 0 p - 2 = 0 p = 2 p + 15 = 0 p = -15 Solution set: p = –15, p = 2

p^2 + 13p – 30 = 0
(p - 2)(p + 15) = 0
p - 2 = 0
p = 2
p + 15 = 0
p = -15

Solution set: p = –15, p = 2
