Pág. 72 Encuentra los productos de las siguientes multiplicaciones
(5a+3b)(5a-3b)= 25a2 -15ab+15ba- 9b2= 25a2 -9b2
(8x+3y)(8x-3y)= 64x2-24xy+24yx-9y2
= 64x2-9y2
(3x+2)(3x-2)= 9x2-6x+6x-4
= 9x2-4
(2m-3)(2m+3)=4m2+6m-6m-9
= 4m2-9
(4x-2)(4x+2)= 16x2+8x-8x-4
= 16x2-4
(2x-5y)(2x+5y)= 4x2+10xy-10yx-25y2
= 4x2-25y2(0.5x+0.2y)(0.5x-0.2y)= 0.25x2-0.1xy+0.1yx-0.04y2
= 0.25x2-0.04y2
(5m+3n)(5m-3n)= 25m2-15mn+15nm-9n2
=25m2-9n2
(0.2x-0.3y)(0.2x+0.3y)= 0.04x2+0.06xy-0.06yx-0.09y2
= 0.04x2-0.09y2
(3m+2n)(3m-2n)= 9m2-6mn+6nm-4n2= 9m2-4n2
