The expression is likely 4x2 - 36x +81 which is the same as (2x - 9)(2x - 9) or (2x - 9)2

9a verbal expression

4x2 - 36x + 81 = 4x2 - 18x - 18x +81 = 2x(2x - 9) - 9(2x - 9) = (2x - 9)2

(2x - 9)(2x +9)

19-3 in a verbal expression = 16

If that's + 81, the answer is (2x - 9)(2x - 9) or (2x - 9)2 If that's - 81, it gets ugly in a hurry.

3^(-2x + 2) = 81? log(3^(-2x + 2)) = log(81) (-2x+2)log(3) = log(81) -2x = log(81)/log(3) - 2 x = (-1/2)(log(81)/log(3)) + 1

The difference is that an algebraic expression has numbers, symbols and variables, but a verbal expression has only words.

2x - 81 = 0 Add 81 to both sides. 2x - 81 + 81 = 0 + 81 Substitute, -81 + 81 cancels out. 2x = 81 Divide by 2. x = 40.5 Above answer would be correct if your question was 2x but it was x2 so using the same method you would get x2 = 81 here the opposite of the square is the square root x = 9
