6 - 9n + 9n^2
factorize
a(3u-v)+a(u+2v)
$\sqrt{\-20y}$
the function of f is such that
f(x)=9x-w
work out the value of f(4)
hence or otherwise, work out the value of f^-1(34)
$\sqrt{\}$ 80
square root of negative 20 y end root
3(2-3p)=42
Calcular los ppuntosextremosde f(x)=5x^4-10x^2
lim x->a (x^2 - sqrt(a^3x))/(sqrt(ax))-a
7=12
20=38
2=2
10=?
