28x^2+82x+30
take 2 common
2( 14 x^2 + 41 x + 15)= 0
now , 2 will go to RHS and become zero as it gets divided by 0.
so , 14 x^2 + 41 x + 15= 0
now factorize it ....
14 x^2 + 6x+ 35x + 15= 0
2x( 7x +3) + 5 (7x + 3)=0
now take ( 7x+3) common .....
(7x+3) [ 2x(1) + 5 (1) ] =0
(7x+3)(2x+5) = 0
x= -3/7 or -2/5
