Question

multiply ( 3x + 5y ) ( x - 3 ) step by step explanation pls​

Answer 1

Step-by-step explanation:

\begin{gathered} \rightarrow \sf{(3x + 5y)(2x + 7y)} \\ \\ \rightarrow \sf{ 3x(2x + 7y) + 5y(2x + 7y)} \\ \\ \rightarrow \sf { {6x}^{2} + 21xy + 10xy + {35y}^{2}} \\ \\{ \rightarrow\boxed{ \sf { {6x}^{2} + 31xy + {35y}^{2} }}}\end{gathered}

→(3x+5y)(2x+7y)

→3x(2x+7y)+5y(2x+7y)

→6x
