Question

I need help again on alg

Answer 1

\[\left( x \sqrt{y+z} \right)\left( x \sqrt{y-z} \right)\]

Answer 2

this is multiplication, with 4 items. you can change their order
x * x * sqrt(y+z) * sqrt(y-z)

Answer 3

okay so x^(2)

Answer 4

you can also write it as
\[ x^2 \sqrt{(y+z)(y-z) } \]

or multiply out the stuff in side the square root using FOIL
It is not any simpler, just different:
\[ x^2 \sqrt{y^2 -z^2 } \]

Answer 5

so would it b x^(2)y-z^(2)
