That would be 12x^3-16x^2+3x-4
One thing wrong is there is not closing parenthasees after x+1
and also, if you multiply it out, the answer is not 8x^2-8x-16 so the factored form given is worng
the real factored out form is 8(x-2)(x+1)
that person forgot the 8 in the front
Answer is
Point-slope form: y + 1 = 4(x -1)
Assuming you wanted
Slope-intercept form: y = 4x -5
Step by step
y - - 1 = 4(x -1)
y + 1 = 4(x -1)
y + 1 = 4x -4
y = 4x -5
Use the quadratic formula to solve the equations . you will get the answers
