Question

Desenvolva o produtos notáveis e reduza os termo semelhantes

a) (10x+y)^2

b) (3y+3x)

c) (5+n^3)^2

Answer 1

a)
$(10x + y) {2} \\ (10x + y) \times (10x + y) \\ 100x + 10 xy + 10xy + y {}^{2} \\ 100x + 20xy + y {}^{2}$
b)
$(3y + 3x) {}^{2} \\ (3y + 3x) \times (3y + 3x) \\ 9y {}^{2} + 9xy + 9xy + 9x {}^{2} \\ 9 {y}^{2} + 18xy + 9x {}^{2}$
c)
$(5 + n {}^{3} ) {}^{2} \\ (5 + n {}^{3} ) \times (5 + n {}^{3} ) \\ 25 + 5n {}^{3} + 5n {}^{3} + n {}^{6} \\ 25 + 10n {}^{3} + n {}^{6}$
