Question

AYUDA URGEE DOY CORONA

Answer 1

Respuesta:

$a. \: \\ 2(16 {y}^{2} + 12) = 32 {y}^{2} + 24 \\ \\ b. \: \: b + c \\ \\ (16 {y}^{2} + 12) + (7 {y}^{2} - 5y + 4) = 23 {y}^{2} - 5y + 16$

c) C-D

$(7 {y}^{2} - 5y + 4) - (1 {y}^{3} + 6y - 1) = \\ - 1 {y}^{3} + 7 {y}^{2} - 11y + 5$

d) A xB

$3 {y} (16 {y}^{2} + 12) = 48 {y}^{3} + 36y$

e) B /4

$\frac{16 {y}^{2} + 12 }{ 4} = 4 {y}^{2} + 3$

f) D x C

$(7 {y}^{2} - 5y + 4)(1 {y}^{3} + 6y - 1) = \\ 7 {y}^{5} - 5 {y}^{4} + 4 {y}^{3} + 42 {y}^{3} - 30 {y}^{2} - 24y - 7 {y}^{2} + 5y - 4 = \\ 7 {y}^{5} - 5 {y}^{4} + 46 {y}^{3} - 37 {y}^{2} - 19y - 8$
