Question

(3 m p square minus 4 n square) (4np minus 4 m square)​

Answer 1

Hey mate!!

$(3mp{}^{2}-4n{}^{2})(4np-4m{}^{2}$

$3mp{}^{2}(4np-4m)-4n{}^{2}(4np-4m{}^{2})$

$12mnp{}^{3}-12m{}^{2}p-16n{}^{3}p+16n{}^{2}m{}^{2}$

Hope it's help uh

Answer 2

Answer:

$12mn {p}^{3} - 12 {m}^{3} {p}^{2} - 16 {n}^{3} p + 16 {m}^{2} {n}^{2}$

Step-by-step explanation:

$= > (3m {p}^{2} - 4 {n}^{2} )(4np - 4 {m}^{2} ) \\ \\ = > 3m {p}^{2} (4np - 4 {m}^{2} ) - 4 {n}^{2} (4np - 4 {m}^{2} ) \\ \\ = >(3m {p}^{2} )(4np) - (3m {p}^{2} )(4 {m}^{2} ) \\ \: \: \: \: \: \: \: \: - (4 {n}^{2} )(4np) + (4 {n}^{2} )(4 {m}^{2} ) \\ \\ = > \: 12mn {p}^{3} - 12 {m}^{3} {p}^{2} - 16 {n}^{3} p + 16 {m}^{2} {n}^{2}$
