Verify whether there exist values for the real$-$valued parameters $k$ and $l$ for which the following three polynomials

$p_1(x)=2+kx+6x^2,p_2(x)=l+5x+3x^2,p_3(x)=1+2x+3x^2$

are orthogonal in the inner product space $P_2$ with inner product

$($:$p(x),q(x)$:$)={\displaystyle \underset{i=0}{\overset{2}{}}}(i+1)a_i{b}_i$ for $p(x)={\displaystyle \underset{i=0}{\overset{2}{}}}{a}_i{x}^i$ and $q(x)={\displaystyle \underset{i=0}{\overset{2}{}}}{b}_i{x}^i.$
