Question 37968: Solve the quadratic equation by factoring and applying the property "ab=0 if and only if a=0 or b=0"
(x^2)+3kx-(10k^2)=0

Solve by factoring:
x%5E2%2B3kx-10k%5E2+=+0
%28x-2k%29%28x%2B5k%29+=+0 Apply the "zero products principle" (ab = 0, iff a = 0 and/or b=0)
x-2k+=+0 and/orx%2B5k+=+0
Ifx-2k+=+0 then x+=+2k
Ifx%2B5k+=+0 then x+=+-5k
P.S. iff means "if and only if"
