Find the point(s) on the surface at which the tangent plane is horizontal. −3x2−2xy y2 4x−3y z 2=0

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
