Question

(7m+6) (6m^2+4m+4) I really suck at math

Answer 1

$\large\mathfrak{{\pmb{\underline{\orange{Your\:answer }}{\orange{:}}}}}$

$:⟼  (7m + 6)(6 {m}^{2} + 4m + 4)$

$:⟼  7m \: (6 {m}^{2} + 4m + 4) + 6 \: (6 {m}^{2} + 4m + 4)$

$:⟼  42 {m}^{3} + 28 {m}^{2} + 28m + 36 {m}^{2} +24 m + 24$

$:⟼  42 {m}^{3} + 28 {m}^{2} + 36 {m}^{2} + 28m + 24m + 24$

$:⟼  42 {m}^{3} + 64 {m}^{2} + 52m + 24$

$:⟼  2(21 {m}^{3} + 32 {m}^{2} + 26m + 12)$

Answer 2

Answer:

$42 {m}^{3} + 64 {m}^{2} + 52m + 24$

Step-by-step explanation:

$(7m + 6)(6 {m}^{2} + 4m + 4)$

$= 7m(6 {m}^{2} + 4m + 4) + 6(6 {m}^{2} + 4m + 4)$

$= 42 {m}^{3} + 28 {m}^{2} + 28m + 36 {m}^{2} + 24m + 24$

$= 42 {m}^{3} + 64 {m}^{2} + 52m + 24( ans)$
