Match the following columns:
P
The tangent \( y=a x^{2}+b x+10 \) at \( (1,2) \) is parallel
W to the normal at the point \( (2,3) \) on the curve \( y=x^{2}+6 x+20 \). Then
Column-I Column-II

(2) The value of \( b \) is (Q) \( -159 / 10 \)
(3) The value of \( 2 a+b \) is (R) -8
(4) The value of \( a+b \) is (S) \( -1 / 10 \)
