You can put this solution on YOUR website! 2X^2+13X+6...............QUADRATIC EQUATION SUM =13 PRODUCT =6*2=12
SO NUMBERS ARE 12 ,1
AS 12+1=13&12*1=12
=2X^2+12X+X+6
=2X(X+6)+6(X+2)
(X+2)(2X+6)
2K^2-7K+6.....................SUM=-7 PRODUCT=12 NOS.=-4,-3
2K^2-4K-3K+6
2K(K-2)-3(K-2)
(K-2)(2K-3)
2X^2+7X-4................SUM=7 PRODUCT=-8 NOS=8,-1
2X^2+8X-X-4
2X(X+4)-(X+4)
(2X-1)(X+4)
