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

then, to solve for p, let p+15=0 and p-2=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 ...
