Astudent performed the following steps to find the solution to the equation x^2-2x-8=0. where did the student go wrong?

step 1. factor the polynomial into (x-4) and (x-2)
step 2. x-4=0 and x-2=0
step 3. x=4 and x=3

a. the student did not make any mistakes, the solution is correct
b. in step 1
c. in step 2
d. in step 3

Is there a direction u in which the rate of change of f(x,y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
