a. Find the solution u(x, y)of Laplace’s equation in the rectangle 0 b. Find the solution if g(x)=x,0≤x≤a/2,a−x, a/2≤x≤a.
c. Fora=3 and b=1, plot u versus x for several values of y and also plot u versus y for several values of x.
d. Plot u versus both x and y in three dimensions. Also draw a contour plot showing several level curves of u(x, y)in the xy-plane.

the answer is 11.2 (i know i’m late)

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

answer: 100
