Step-by-step explanation:
(4x+7)(2x+5)
We would have to multiply each term in the first bracket by the term in the second bracket.
4x(2x+5)+7(2x+5)
So now we multiply 4x by 2x and 5
8x+10x
8x+10x+7(2x+5)
And then we multiply 7 by the 2x and the 5
14x+35
8x+10x+14x+35
So now we proceed to add since like terms have already been combined
18x+14x+35
32x+35
