Solve for -4x-4=-4(x+2)​
Sergeu [11.5K]

Answer:

no solutions

Step-by-step explanation:

-4x-4=-4(x+2)​

Distribute the negative

-4x-4 = -4x-8

Add 4x to each side

-4x+4x-4 = -4x+4x-8

-4 = -8

Since this is not true there are no solutions

Write a polynomial function f of the least degree that has rational coefficients,
mina [271]

Answer:

f(x)=x^4+15x^2-16

Step-by-step explanation:

It is given that the leading coefficient of the polynomial is 1.

We need to find a polynomial function f of the least degree.

If c is a root of a polynomial then (x-c) is a factor of the polynomial.

The given zeros are -1, 1, -4i, 4i. So,

f(x)=(x-1)(x+1)(x+4i)(x-4i)

f(x)=(x^2-1^2)(x^2-(4i)^2)

f(x)=(x^2-1)(x^2+16)      [\because i^2=-1]

f(x)=x^2(x^2+16)-1(x^2+16)  

f(x)=x^4+16x^2-x^2-16  

f(x)=x^4+15x^2-16  

Therefore, the required polynomial is f(x)=x^4+15x^2-16 .
