Integrate (x^3)/(a^2)-(x^2) ?

notka56 [123]

Hi!

$\frac{x^3}{(a^2)-(x^2)}$

<em>First remove parenthesis.</em>

$\frac{x^3}{a^2-x^2}$

<em>Factor $a^2-x^2$ or $(x+a)(a-x)$ </em>

$=\frac{x^3}{(a+x)(a-x)}$

Hope this helps! Thank you for posting your question at here on Brainly. Have a great day.

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

Given that a, b and c are positive integers, and abc=210, what is least possible sum for a+b+c

Vesnalui [34]

Answer:

The least possible sum for a+b+c is 18.

Step-by-step explanation:

As given a,b and c are positive integers and abc = 210

So, let us consider some situation in which the product abc = 20

If a, b and c are 5, 6 and 7 then

abc = 210 & a+b+c = 18

If a, b and c are 3, 7 and 10 then

abc = 210 & a+b+c = 20

If a, b and c are 7, 15 and 2 then

abc = 24 & a+b+c = 24

If a, b and c are 2, 5 and 21 then

abc = 210 & a+b+c = 28

From all of the above situation the least sum is 18 when a, b and c are 5, 6 and 7 respectively.
