tangent of 12x^2-8x-4

tangent of

12 x^{2} - 8 x - 4

y = (24 a_{0} - 8) x - 12 a_{0}^{2} - 4

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, 12 a_{0}^{2} - 8 a_{0} - 4)

Find the slope of

y = 12 x^{2} - 8 x - 4 : \frac{d y}{d x} = 24 x - 8

EN : T i tl e G e n er a l Eq u a t i o n Sl o p e A t P o in t 2 Eq : m = 24 a_{0} - 8

Find the line with slope m=

24 a_{0} - 8

and passing through

(a_{0}, 12 a_{0}^{2} - 8 a_{0} - 4) : y = (24 a_{0} - 8) x - 12 a_{0}^{2} - 4

y = (24 a_{0} - 8) x - 12 a_{0}^{2} - 4

What is the tangent of 12x^2-8x-4 ?
The tangent of 12x^2-8x-4 is y=(24a_{0}-8)x-12a_{0}^2-4
