Show an equation of the tangent to the curve π¦ = π₯^5 β 3π₯^2 +π₯ + 5 at the point (β1, 0) is given by π¦ = 12(π₯ +1) by differentiation

y' = 5x^4 - 6x + 1

The slope of the tangent line at (-1,0) is

y' (-1) = 5(-1)^4 - 6(-1) + 1 = 12

The equation of the tangent line to (-1,0) is

y = 12 ( x - 1) + 0

y = 12(x - 1)
