Question

what's h times hx?

Answer 1

h^2x

Answer 2

h times hx is \[\Large h*hx = h^2x\]


This is assuming that hx is made of two separate variables (h and x).

Answer 3

\[ h^{2}x\]

Answer 4

yep

Answer 5

i thought it was hx^2

Answer 6

no wait i meant x times xh

Answer 7

\[\Large x*xh = x^2h\]

Answer 8

can u help me, how would one factor a cubed for example
(x+h)^3?

Answer 9

you mean expand?

Answer 10

yes

Answer 11

(a+b)^3 = a^3 + b^3 + 3ab(a+b)

Answer 12

\[\Large (x+h)^3\]


\[\Large (x+h)(x+h)(x+h)\]


\[\Large (x^2+2xh+h^2)(x+h)\]


\[\Large (x+h)(x^2+2xh+h^2)\]


\[\Large x(x^2+2xh+h^2)+h(x^2+2xh+h^2)\]


\[\Large x^3+2x^2h+xh^2+hx^2+2xh^2+h^3\]
So \[\Large (x+h)^3 = x^3+2x^2h+xh^2+hx^2+2xh^2+h^3\]

Answer 13

thank you both for the help!
