    Inner product problem

    I'm having trouble justifying the inner product

    Intergral from 1 to 0 of p(X)q(x)
    where
    p(x)=ao+a1x+a2x
    Q(x)=b0+b1x+b2x

    Ive satisfied all conditions apart from
    Intergral from 1 to 0 of p(X)^2 >=0
    how do I justify a^2 + b^2 +c^2 +2ab+2ac+2cb is above the x axis?
    where a=a0
    b=a1
    c=a2

    It is the integral of p(x)^2\geq 0 ...!! What do you have to develop the square for?
