Please answer the one this exercises if you can send photos sent it pls and you have to use quadratic function for these Thanks

The expression of the equation will be:
x² - 8x = x(x - 8)
x² - 10x = x(x - 10)
x² - 5x = x(x - 5)
x² - 3x = x(x - 3)
It should be noted that an equation simply means the expression of the variables that are given.
In this case, the following can be represented:
x² - 8x = x(x - 8)
x² - 10x = x(x - 10)
x² - 5x = x(x - 5)
x² - 3x = x(x - 3)
This is illustrated above.
