Find the value of k such that the equation of the tangent line to f(x) = x^2 + k*x is equal to y = 5*x + 3

Find the value of k such that the equation of the tangent line to f(x) = x^2 + k*x is equal to y = 5*x + 3

Answer

The equation x 2+kx=5x+3 must have only one solution for the line y to be a tangent line to the quadratic function f x.
x 2+kx=5x+3 x 2+kx-5x-3=0 x 2+ k-5 x-3=0 Delta= k-5 2-4 cdot1 cdot -3 = k-5 2+12 k-5 2+12=0 k-5 2... So there isn't such value of k.
