domains and squares

300

find the domain:

f(x)=root()(x+6)/(x-5)

{xsubR |x>=-6,xne5}

400

solve by completing the square:

4x^2+3x-2=0

-3/8pmsqrt(41)/8

500

find the domain:

f(x)=(sqrt(2x+6))/(4x^2-4x-3)

{xsubsetreal | x>=-3,xne-1/2,3/2}

300

if f(x) = x² - 2x, find f(x - h).

x^2-2xh+h^2-2x+2h

400

Solve for x:

(7!)/(4!x!)=35

x=3

500

(root(3)(a)root()(b)(root(4)(ab))^3)/(a^-2b^3(root()(a))^3b^-2

a^(19/12)b^(1/4)

400

solve for x:

y=3((px+2)/(r+5x))

x=(6-yr)/(5y-3p)
