Assuming you meant 19×2


4x(3x − 7) − 19×2 = 12[tex]x^{2}[/tex]-28x-38


If not just reply

Answer:  The required simplified form is [tex]-7x^2-28x.[/tex]

Step-by-step explanation:  We are given to simplify the following expression :

[tex]E=4x(3x-7)-19x^2~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We will try to simplify the bracket first an then will combine the terms as much as possible.

From (i), we have

[tex]E\\\\=4x(3x-7)-19x^2\\\\=12x^2-28x-19x^2\\\\=-7x^2-28x.[/tex]

Thus, the required simplified form is [tex]-7x^2-28x.[/tex]
