$1.13m + 26m {}^{2} - 39m {}^{3}$

$2.17x {}^{2} + 34x + 51$
$3.18m {}^{2}n {}^{4} - 12m {}^{2}n {}^{3} + 24m {}^{2}$
$4.10x {}^{2}y - 15y {}^{2}$
what is the answer fot this?

Answer:

$1.13m + 26m {}^{2} - 39m {}^{3}$

=13m (1 + 2m - 3m ^{3})

$2.17x {}^{2} + 34x + 51$

= 17 (x^2 + 2x + 3)

$3.18m {}^{2}n {}^{4} - 12m {}^{2}n {}^{3} + 24m {}^{2}$

=6m^2 (3n^4 - 2n^3 + 4)

$4.10x {}^{2}y - 15y {}^{2}$

= 5y (2x^2 - 3y)
