A quadratic polynomial `p(x)` is given as `p(x)=x^2-5x + 6`, then find the maximum value of `(p(cosx))/2`

If sum of squares of zeroes of a quadratic polynomial is: p(x)=x^(2)-8x+k is -40 then find the value of k

If p(x) = x^(2) - 5x -6 , find the value of p(3).

If the quadratic polynomial p(x) is divisible by x - 4 and 2 is a zero of p(x) then find the polynomial p(x).

p(x) = x^(2)-5x-6 , find the value of p(2)

p(x) = x^(2)-5x-6 , find the value of p(-2) .

p(x) = x^(2)-5x-6 , find the value of p(1)

p(x) = x^(2)-5x-6 , find the value of p(-1) .

p(x) = x^(2)-5x-6 , find the value of p(-3) .

If the sum of squares of zeroes of the quadratic polynomial p(x)=x^2-8x+k are 40 then find the value of k.

p(x) = x^(2)-5x-6 , find the value of p(3) .
