Question

Find the product: (2x +5)(2x -7)​

Answer 1

Answer + EXPLANTION:

first, we open the first bracket and multiply accordingly

2x(2x-7) + 5(2x-7)

so 2x multiply 2x gives 4x² and 2x multiplied with (-7) gives (-14x)

= 4x² - 14x + 5(2x-7)

now we multiply 5 bu 2x ad get 10x and multiply 5 to (-7) and get (-35)

= 4x² - 14x + 10x - 35

adding the like terms we have,

=4x² - 4x - 35

so the answer is 4x² - 4x - 35
