If f(x)=4x^2+1 and g(x)=x^2-5 find(f+g)(x)

Zepler [3.9K]

Answer:

$\large\boxed{(f+g)(x)=5x^2+6}$

Step-by-step explanation:

$(f+g)(x)=f(x)+g(x)\\\\f(x)=4x^2+1,\ g(x)=x^2-5\\\\\text{Substitute:}\\\\(f+g)(x)=(4x^2+1)+(x^2-5)\\\\=4x^2+1+x^2-5\qquad\text{combine like terms}\\\\=(4x^2+x^2)+(1+5)\\\\=5x^2+6$

Divide the polynomials. Your answer should be in this form p(x)+k/ x-3 where p is a polynomial and k is an integer. x^2+4/x-3=

Makovka662 [10]

Answer:

x + 3 + $\frac{13}{x-3}$

Step-by-step explanation:

Using long division

x + 3 ← quotient

--------------------------

x - 3 | x² + 0x + 4

x² - 3x ↓

------------------------

3x + 4

3x - 9

-----------------------

13 ← remainder

Thus

$\frac{x^2+4}{x-3}$ = x + 3 + $\frac{13}{x-3}$
