01- Calcule os seguintes produtos notáveis

a) (a+b)^2=
b) (x+y)^2=
c) (a+3x)^2=
d) (x+7)2=
e) (5+2m)^2=

ME AJUDEM URGENTEEEEEE

Answer 1

a) (a+b)^2= a² + 2ab + b²

b) (x+y)^2= x² + 2xy + y²

c) (a+3x)^2= a² + 6ax + 9x²

d) (x+7)2= x² + 14x + 49

e) (5+2m)^2= 25 + 20m + 4m²

Answer 2

a)

${(a + b)}^{2} = (a + b)(a + b) = {a}^{2} + 2ab + {b}^{2}$

b)

${(x + y)}^{2} = (x + y)(x + y) = {x}^{2} + 2xy + {y}^{2}$

c)

${(a + 3x)}^{2} = (a + 3x)(a + 3x) = {a}^{2} + 6ax + 9{x}^{2}$

d)

${(x + 7)}^{2} = (x + 7)(x + 7) = {x}^{2} + 14x + 49$

e)

${(5 + 2m)}^{2} = (5 + 2m)(5 + 2m) = 25 + 20m+ 4{m}^{2}$
