The correct simplified expression is [tex]\rm 28x^3-33x^2-33x+18[/tex].
Given
Polynomial; [tex]\rm (7x - 3)(4x^2 -3x - 6)[/tex]
Multiplication is the process of calculating the product of two or more numbers. The multiplication of numbers say, ‘a’ and ‘b’, is stated as ‘a’ multiplied by ‘b’.
Then,
The correct simplification of the expression is;
[tex]\rm \rm (7x - 3)\times (4x^2 -3x - 6)\\\\7x(4x^2 -3x - 6)-3(4x^2 -3x - 6)\\\\ 28x^3-21x^2-42x-12x^2+9x+18\\\\28x^3-33x^2-33x+18[/tex]
Hence, the correct simplified expression is [tex]\rm 28x^3-33x^2-33x+18[/tex].
