Question

Multiply using Vertical method: $(5m-7)(3m-6)$

Step-by-Step Solution

Answer

$$\begin{gathered} Multiply the binomials ,we get \\ (5m-7)(3m-6)=15m^2-51m+42 \end{gathered}$$

Step 1

$$\begin{gathered} Given Information \\ (5m-7)(3m-6) \end{gathered}$$

Step 2

Vertical addition is a method of adding where the numbers are lined up in columns according to their places value. 

Part(a) Step1.Multiply the binomials using vertical method

$$\begin{gathered} \left(a\right) \\ It doesn\text{'}t matter which binomial goes on top \\ 5m-7 \\ \frac{ \times 3m-9}{Multiply 5m-7 by -6 -30m+42 partial product } \\ \frac{Multiply 5m-7 by 3m 15m^2-21m partial product}{Add like terms 15m^2 -51m+12 } \end{gathered}$$
