Question

the expression (secx+tanx)2 is the same as ______

Answer 1

\(\huge\color{green}{{\rm welcome}~\rm to~open~study!!:)}\)

Answer 2

for example
\(\huge\color{red}{{\rm (a+b)^2}~}\) \(\huge\color{red}{\rm = (a+b)(a+b)}\)
its mean you have same two order pair
then you have to multiply
yu can use foil method

Answer 3

and remember this
\(\huge\color{orange}{{\rm (a+b)^2}~}\) = \(\huge\color{orange}{{\rm a^2+}~\rm2ab+b^2}\)

Answer 4

i"m sorry I'm a little stuck can you do the first step please?

Answer 5

its oky :)
okay first you should expand the bracket
you know secx= ???
and tanx= ??

Answer 7

yesh that's right so
