What is the middle product of (-2x + - 5)?

7x

-3x

-7x

In the expression (-2x + 1)(-3x - 5) the middle product is 7x .

Step-by-step explanation:

As given the expression in the question be as follow .

= (-2x + 1)(-3x - 5)

Simplify the above terms

= -2x × (-3x - 5) + 1 (-3x - 5)

Now open the bracket

= -2x × -3x -2x × -5 -3x - 5

= 6x² + 10x -3x - 5

= 6x² + 7x - 5

In the above eqution the middle product is 7x .

Therefore in the expression (-2x + 1)(-3x - 5) the middle product is 7x .
