3x^4+7x^3+69x^2+175x-150
Find all zeros(real and complex)
I managed to factor out x^2+25 which gives me 2 of the zeros: 5i, -5i
After which I have (x^2+25)(3x^2+7x-6)
I'm stuck at factoring 3x^2+7x-6; When I try to complete the square I get different zeros than if I use the Rational Zeros Theorem. Any tips or ideas?
