25 POINTS ANSWER FAST!

First one is true , because by grouping method , it is justified.

Second one is false , because by putting 5x- 3 and 2x+1 = 0 , we get solutions 3/5 and -1/2 not 1/2

Third is true as I told above 3/5 is one of the zero.

I hope this all helps you : )

5x(2x + 1) - 3(2x + 1) = 0

<=> (5x - 3)(2x + 1) = 0 => Option 1 is true.

<=> 5x - 3 = 0 or 2x + 1 = 0

<=> 5x = 3 or 2x = -1

<=> x = 3/5 or x = -1/2

=> Option 2 is false.

=> Option 3 is true.

Hope this helps!
