Find a thrid degree polynomial equation with rational coeffcients that has roots -4 and 6 +i

For the coefficients to be rational, any complex roots must occur in conjugate pairs. So if 6+i is a root, then so must be 6-i.

Now such a third degree polynomial might be

(x+4)(x-(6+i))(x-(6-i))=(x+4)(x^2-12x+37)=x^3-8x^2-11x+148

The only variation to this would be multiplying throughout by some non-zero constant. This doesn't change the roots.

Find the value of x. 6 8 4 x
snow_tiger [21]
Answer:

3

Explanation:

4 is half of 8 on the right side, so that means X has to be half of 6, so it’s 3. Also, it couldn’t be 2 because it is too big, and it can’t be 4 because it isn’t the same length as the other 4, so it’s 3
