Answer:

1+6i

Step-by-step explanation:

Given:

f(x)=x^4 - 2x^3 + 38x^2 - 2 + 37

zero of f(x) = 1-6i

another zero of function = ?

Conjugate Zero theorem:

As per conjugate zero theorem, if a function f(x) has real coefficients and one of zero is a complex number then the conjugate of that complex number will also be a zero of that function i.e. complex zeroes will occur in complex conjugate pairs.

conjugate of 1-6i is 1+6i

hence another zero of f(x) will be 1+6i !

How might we know whether x is a positive number, negative number, or zero, without solving the equation? 5x = -16.5​
pochemuha
To be able to get the negative number you have to divide x by a negative number to get your result. Seeing the solution is a negative number but your left side of the equation is a positive number tells us we have to divide by a negative number on the left side and right to give us the solution...
