write a polynomial fuction f of least degree that has rational coefficients, a leading coefficient of 1, and the zeroes of 6,-3,

Amanda [17]

Answer:

$f(x)=x^3-7x^2-6x+72$

Step-by-step explanation:

$f(x)=a(x-p)(x-q)(x-r)\\\\f(x)=1(x-6)(x+3)(x-4)\\\\f(x)=(x^2-3x-18)(x-4)\\\\f(x)=x^3-4x^2-3x^2+12x-18x+72\\\\f(x)=x^3-7x^2-6x+72$

This is because $x=6$ is the solution to $x-6=0$ , $x=-3$ is the solution to $x+3=0$ , and $x=4$ is the solution to $x-4=0$ .

outer: x times 2=2x

inner: 3 times x=3x

last: 3 times 2=6

so x^2+2x+3x+6

combine like terms
