Question

7x(x-4)-x(6-x)=.............​

Answer 1

Ответ:

7х(х-4)-х(6-х)=7х²-28х-6х+х²=8х²-34х

Answer 2

Let's simplify the expression step by step:

7x(x - 4) - x(6 - x)

First, distribute the 7x and -x within each set of parentheses:

7x * x - 7x * 4 - x * 6 + x^2

Now, simplify each term:

7x^2 - 28x - 6x + x^2

Combine like terms:

7x^2 + x^2 - 28x - 6x

8x^2 - 34x

So, 7x(x - 4) - x(6 - x) simplifies to 8x^2 - 34x.
