Question

Obtain all other zeroes of f(x) = x^3+13x^2+32x+20, if one of its zeroes is -2

Answer 1

Hello Mate!

What do you mean by zeros?

This means that final value of f(x) will be "0". If value of x is - 2 so here factor is ( x + 2 ).

Either method is factor theorum for putting different values in answer. But one simple method is manual divsion.

Hence, other zero's are x = - 2 ( Given ), - 1 and - 10.

Thanks for your question!

Have great future ahead!
