the factors are (p + 3) and (p + 4)

for the product of the factors to be >0 ; either both factors are >0 , OR both factors are <0

p + 3 > 0 ___ p > -3
p + 4 > 0 ___ p > -4

p + 3 < 0 ___ p < -3
p + 4 < 0 ___ p < -4

p must be > -3 AND -4 (which means greater than -3) , OR < -3 AND -4 (which means less than -4)
