Algebra 2 problem help?
I need to find the x-intercepts and y-intercept of this polynomial equation. I know to set Y=0 and then X=0, but am having problems with the x-intercepts. What do I do after I subtract 96 to the equation's other side?? Please help, I'm having so much trouble! Thank you
Y= 7x^5 + 10x^3 + 19x + 96

y = 7x^5 + 10x^3 + 19x + 96
The x_intercept is when:
0 = 7x^5 + 10x^3 + 19x + 96
- 96 = 7x^5 + 10x^3 + 19x ... so clearly "x" must be negative
This equation does not factor:
... the only real (computer) solution is approximately: -1.41988
