Answer:

The expansion of ( 11x + 18 ) ( 11x - 18 ) will be 11x(11x-18) + 18(11x-18)Here x is not equal to multiplication. Here x is variable.

If you want to solve this expression you can solve it with (III) algebraic identity.

(III) Algebraic identity :-

(a+b)(a-b) = a²- b²

Hope it helps you. Have a good day and please mark me as brainliest.
