p^2+13p30=0
for this the first thing you gotta do is to FACTORISE:
so,
(p + 15)(p – 2) = 0
from the equation above you can deduce that:
p + 15 = 0
or,
p – 2 = 0
therefore, p = 15 or 2.
as simple as that. good luck and have fun with math!

p^2 + 13p – 30 = (p + 15)(p – 2)
p = 15 or 2

15 and +2 …
here’s how to solve it:
1st, you have to factor them out (i find this easiest for this type of equation; there are other two ways: completing the square and quadratic formula), so the new equation looks like this:
(p+15)(p2)=0
then, to solve for p, let p+15=0 and p2=0, since the two factors are under a multiplication operation, and 0 multiplied by anthing will be equal to 0.
so, the p=15 and p=2 …

2 ^ 2 + 13 x 2 – 30 = 0
p = 2

p=*square root sign over30/13 divided by 2

(p+15)(p2)=0
so p=15 or 2
