Question

3(m+2n)sq-2(m+2n)-16​

Answer 1

Answer:

$3(m + 2n) {}^{2} - 2(m + 2n) - 16 \\ \\ (m + 2n)((3(m + 2n - 2)) - 16 \\ \\ (m + 2n)(3m + 6n - 6) - 16 \\ \\ 3 {m}^{2} + 6mn - 6m + 6mn + 12 {n}^{2} - 12n - 16 \\ \\ 3 {m}^{2} + 12mn - 6m - 12n - 16$

Answer 2

Answer:

3(m+2n) ² - 2(m+2n) -16

(m+2n) [3(m+2n-2)]-16

(m+2n) (3m+6n-6)-16

n²+6mn-6m+6mn+12n²-12n-16

3m²+12mn-6m-12n-16
