Heya !!
25X² + 30X - 7 = 0
25X² + 35X - 5X - 7 = 0
5X ( 5X + 7 ) - 1 ( 5X + 7 ) = 0
( 5X + 7 ) ( 5X - 1 ) = 0
( 5X + 7 ) = 0 OR ( 5X - 1 ) = 0
X = -7/5 OR X = 1/5.
25X² + 30X - 7 = 0
25X² + 35X - 5X - 7 = 0
5X ( 5X + 7 ) - 1 ( 5X + 7 ) = 0
( 5X + 7 ) ( 5X - 1 ) = 0
( 5X + 7 ) = 0 OR ( 5X - 1 ) = 0
X = -7/5 OR X = 1/5.

Hey!!
25x^2 + 30x + 7 = 0
=> 25x^2 + 35x - 5x + 7 = 0
=> 5x ( 5x + 7 ) - 1 ( 5x + 7 ) = 0
=> ( 5x + 7 )( 5x - 1 ) = 0
=> ( 5x + 7 ) = 0 OR ( 5x - 1 ) = 0
=> x = - 7 / 5 OR x = 1 / 5
