Question

Yooo im from k12 please help me rqqq!!!

Answer 1

$\\ \tt\hookrightarrow 12x^4(-56x^3y^2)$

$\\ \tt\hookrightarrow -672x^{4+3}y^2$

$\\ \tt\hookrightarrow -672x^7y^2$

None of the above

Answer 2

$\sf \: 12x^{4} ( - 56x^{3} {y}^{2} )$

Multiplying a positive and a negative equals a negative: (+)×(-)=(-)

$\sf \: { - 12x}^{4} \times 56 {x}^{3} {y}^{2}$

Calculate the product

$\boxed{ \tt - 672x^{7} {y}^{2} }$
