n = fraction 5 over 3

Explanation;
 $\frac{3}{5}n- \frac{4}{5}= \frac{1}{5} n$
Eliminate the demominator by multiplying each term by 5.
3n-4=1
3n=5
n= $\frac{5}{3}$

Write a polynomial function $f$ of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros.

olganol [36]

Answer:

$f(x) = x^{3} + 4x^{2} -7x^{} -10^{}$

Step-by-step explanation:

The zeros of the polynomial function are given us as -5,-1,2

If the zeros of a polynomial function are α,β,ω, the polynomial function can be obtained using the expression below:

f(x) = (x - α)(x - β)(x - ω)

where α = -5, β = -1, and ω = 2

$f(x)=(x-(-5) )(x -(-1))(x - 2) = (x+5)(x+1)(x-2)\\\\f(x)=(x+5)(x^{2} -2x + x -2) = (x+5)(x^{2} -x-2)\\\\f(x)=x(x^{2} -x-2)+5(x^{2} -x-2)\\\\f(x)= x^{3} - x^{2} -2x + 5x^{2} - 5x - 10\\\\f(x)= x^{3} + 4x^{2} -7x - 10$
