Question

whats 9x times x

Answer 1

is this a complete question...?

Answer 2

9x*x =9x^2

Answer 3

9x is a "short" way to write 9 * x
in other words 9 times x
9x*x means 9*x*x

but lots of times, people use the short hand x*x = x^2 \( x \cdot x = x^2 \)
and 9*x*x can be shortened to just
\[ 9 x^2 \]
