Ejercicio 1.4

Resolver:

1.  (2x^2-3y^2)^2

var ('x,y')
(x, y)
expand ((2*x^2-3*y^2)^2)
4*x^4 - 12*x^2*y^2 + 9*y^4

2.  (a^2+3)(a^2-3)

var ('a')
a
expand ((a^2+3)*(a^2-3))
a^4 - 9

3.  (x^2+x+1)(x^2+x-1)

var ('x')
x
expand ((x^2+x+1)*(x^2+x-1))
x^4 + 2*x^3 + x^2 - 1

4.  (a-b+c)(a+b+c)

var ('a,b,c')
(a, b, c)
expand ((a-b+c)*(a+b+c))
a^2 + 2*a*c - b^2 + c^2

5.  (2x+5)(3x-2)

var ('x')
x
expand ((2*x+5)*(3*x-2))
6*x^2 + 11*x - 10

6.  (3m-2n^2)^3

var ('m,n')
(m, n)
expand ((3*m-2*n^2)^3)
27*m^3 - 8*n^6 + 36*m*n^4 - 54*m^2*n^2
