Thread: determine the points on the curve that corresponds to the given slope

determine the points on the curve that corresponds to the given slope

y=(2x-1)(-4+2x^2) slope = 3

i tried simplifying the function
which got me 2x^3-x^2+8x+4
and equate the slope with the function
2x^3-x^2+8x+4=3
which got me
2x^3-x^2+8x-1

now how do i factor this equation and get the x-intercepts? i got stuck here....please here

Expand to get .
Find the derivative(the slope) .
Set equal to 3,
Solve.

so thats how do you it thx a ton
