Solve the formula for the indicated variable.<br> T(r+s)=rs, for r<br> (Simplify your answer.)

yaroslaw [1]

Answer:

$R = \frac{-TS}{(T-S)}$

Step-by-step explanation:

First, distribute all terms

$T(R+S) =RS\\TR + TS =RS$

Get all terms with R onto the same side

$TR + TS = RS\\TR - RS = -TS$

Factor out the R

$R(T-S)=-TS$

Divide by (T-S) to isolate R

$R = \frac{-TS}{(T-S)}$

Three roots of the polynomial equation x4 - 4x3 - 2x2 + 12x + 9 = 0 are 3, -1 and -1. Explain why the fourth root must be a real

LiRa [457]

Descares Theorem says that the number of roots of a polynomial is equal to its highest exponent, and the roots could be real and/or imaginary (complex).

However is their is one complex root (a + i.b), it's conjugate is also
a root (a-i.b).

In the equation x⁴ - 4x³ - 2x² + 12x + 9 = 0, we have already 3 roots, then the 4rth cannot be a complex one since we don't have a fifth for its conjugate.
