Question

2y²+27y+13=0 by formula​

Answer 1

Answer:

2y2 + 27y + 13 = 0

2y2 + 26y + y + 13 = 0

2y(y +13) + 1(y + 13) = 0

= (2y + 1)(y +13)

either, (2y + 1) = 0

2y = -1

y = -1/2

or,

(y + 13) = 0

y = - 13

Answer 2

Step-by-step explanation:

LHS = 2y^2+27y+13

= 2y^2+y+26y+13

= y(2y+1)+13(2y+1)

= (y+13)(2y+1)Ans
