Question 1

--
Choose the correct simplification of the expression -5x2(4x – 6x2 – 3).

Question 2

$\huge \bf༆ Answer ༄$

Let's simply ~

${ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: - 5 {x}^(2) (4x - 6 {x}^(2) - 3)$

${ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:( - 5x {}^(2) * 4x) - ( - 5 {x}^(2) * 6 {x}^(2) ) - ( - 5 {x}^(2) * 3)$

${ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: - 20 {x}^(3) - ( - 30 {x}^(4) ) - ( - 15 {x}^(2) )$

${ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: - 20 {x}^(3) + 30 {x}^(4) + 15 {x}^(2)$

${ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:30 {x}^(4) - 20 {x}^(3) + 15 {x}^(2)$
