Answer:
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 .
