Answer 1

this is the exact answer

Answer 2

Let us take for eg x2 + 7x + 10 now consider 10 to be a product of two numbers and 7 to be a sum of the Same two numbers. In this case the answer is 5 and 2 the product of 5 and 2 is 10 and sum of 5 and 2 is 7 now sub. 5x and 2x in place of 7 x .now the equation is x2 + 5 x + 2 x + 10 now consider x2 + 5x take the common multiple out x( x +5). Now the same in other two terms 2x( x + 5) now take the common multiple out ( x + 5) ( x + 2x) is the answer .
